Back in 2019, I had exactly two months to master Python
2
because somehow I got into this cool research project lab that required Python experience,
3
but I had exactly no experience whatsoever.
4
So not only did I have to learn Python,
5
I had to learn it really well, fast.
6
So in this video, I'm going to show you what I wish I had.
7
The five level Python pyramid designed to take you from zero experience to advanced level in building real Python projects with AI.
8
But please remember, you have to follow this pyramid in order to ensure your foundations are solid.
9
So with that being said,
10
sit back, relax, take notes, and let's get started.
11
The first layer of the pyramid is the base, your fundamentals.
12
Do not start coding right away.
13
Trust me, you'll be shooting yourself in the foot because you must first learn the art of the language,
14
the art of Python.
15
Just like you wouldn't want to wake up one day in France and someone tells you,
16
Hey, start speaking French.
17
No, no, no, no. You want to make sure that you actually learn the language and learn it the right way.
18
So first let's understand Python's syntax.
19
In the real world, we count things like one, two, three, four, five.
20
But in Python, we actually go zero, one, two, three, four.
21
The first number is always zero.
22
It's a zero index based language.
23
So instead of saying, hey,
24
can you give me the first item on the list?
25
You actually say, hey, get me the item at index zero.
26
So the next time someone tells you,
27
oh, you were my first love,
28
that's actually a red flag,
29
because who was number zero?
30
Another thing, say you're going shopping,
31
you might say drive until you reach the store.
32
But in Python, we use what we call a while loop.
33
While you are not at the store, drive.
34
So until the condition of you being at the store is true,
35
you shall continue to drive forever.
36
So it's a bit of a frame of mind difference that I really want you guys to hone in on.
37
But what's more important than actually all the syntax jargon is your overall mindset.
38
In Python, you need to think of yourself as a problem solver,
39
not just a coder.
40
You see, code is a tool.
41
It's a mechanism for you to solve bigger problems.
42
In fact, back in the day when software engineering was first getting started,
43
they used physical punch cards.
44
And coding languages like Python in Java came much later as a mechanism of abstraction to help us write faster,
45
more efficient solutions for our problem.
46
Imagine if you're an artist.
47
If you're a good artist,
48
you want to create visually aesthetic pieces.
49
And you should be skilled enough to do that with a paintbrush,
50
or a crayon, or a color pencil.
51
Everything is just a tool at your disposal.
52
And so if you want to become really good at coding in computer science,
53
it shouldn't matter what language you pick up.
54
The art of you problem solving will forever stay the same.
55
Now that we've laid down our foundations,
56
let's get to the setif layer,
57
and here's where a lot of beginners get lost.
58
A lot of people at this point will tell you,
59
oh, go to your terminal and install brew,
60
then download Python, then download Anaconda,
61
download PIP, download Spyder, download PyTarm,
62
download VS Code, and they'll tell you so many different things to download,
63
because it'll make you this complete high quality programmer.
64
Well guess what, all of that stuff is useless at this stage.
65
You know why?
66
Because I've been through it.
67
download all these different configurations as a beginner programmer,
68
you actually don't even know how to set things up properly.
69
When I was first learning,
70
I downloaded everything and I tried to run Python,
71
but apparently there's a difference between Python 2 and Python 3.
72
And then when you type Python into the terminal,
73
all of a sudden you have to write out code
74
and then you have to know the Python function to exit it was a complete mess
75
and I spent more time trying to be able to write Python code than actually writing Python code
76
but
77
if you want to learn Python quickly the right way the
78
first thing I would do is actually go to Google Colab
79
all you need is a Google account like a Gmail then you open up this environment
80
and you can run any code with any library you would ever need Plus,
81
you don't have to deal with download configuration issues since it handles all of that.
82
Like imagine being a chef and you walk into a kitchen that has every single ingredient you would ever need.
83
Plus, it has pots, pans,
84
dishes, and spatula, Michelin grade quality.
85
Everything you would ever want right there,
86
yeah, I know you'd feel good.
87
So that's your environment.
88
But in terms of the actual tasks you should do at this point,
89
I want you to check out this GitHub repository right here called 30 Days of Python.
90
It's a It's a repository that contains all the fundamental basic Python lessons,
91
and it'll get you all the way to an intermediate level.
92
It starts with your basics and data structures,
93
and then it goes to Python and web applications and API calls.
94
Plus, with every lesson, it gives you tutorials,
95
sample codes, so you can actually take all the information you're getting and execute it in your Google Colab.
96
But beyond just that, I would also recommend using Kodi.tech.
97
This platform gives you a lot of mini bite-sized lessons with actual projects for each one.
98
It's great for Python because it shows you,
99
once again, the lessons and allows you to practice coding in their sandbox environment.
100
Plus it has a mini AI tutor that can help you out if you're ever struggling with anything.
101
And the best part is they're completely free,
102
but they have some premium features like unlimited AI queries.
103
And if you're interested in that,
104
I actually have a discount link in the description down below.
105
Anyways, once you've got a solid grasp of Python,
106
then you can actually go ahead and download all those like complicated configurations into your home laptop environment.
107
You can download Python 3 and install a Visual Studio Code or PyCharm.
108
Really quick, I want you to check out this new Dell Pro Max Tower T2 I recently got.
109
It's an AI powerhouse.
110
The Dell Pro Max Tower T2,
111
powered by the Nvidia RTX Pro 6000 Blackwell GPU, isn't just another desktop.
112
It features the industry's only new chassis designed specifically for AI workloads.
113
These specs enable faster training,
114
smoother inferencing, and real-time performance for the most demanding workflows.
115
With 96 gigabytes of lightning fast memory,
116
it delivers the bandwidth and compute power needed for advanced data visualization,
117
3D rendering, and generative AI development.
118
Simply put, it's the ultimate GPU for creators,
119
developers, and engineers pushing the limits of what AI hardware can do.
120
This is what future-proofing your workflow looks like,
121
taking the advantages of AI in a high-performing environment.
122
Step into the future of work with the Dell Pro Max Tower T2.
123

124
And now back to the video.
125
Now let's get ready to move even faster,
126
and the next layer of our pyramid is real-world projects.
127
You can't claim to be a good chef and not cook anything,
128
and you can't claim to be a good coder and not build anything.
129
We want to see some results quickly.
130
So one of the best resources I found,
131
especially nowadays for learning Python,
132
is this GitHub repository called Practical Tutorials Project Based Learning.
133
A lot of people get stuck in this thing called tutorial hell,
134
where they watch every video,
135
read every textbook, absorb every tutorial over and over and over again until they burn themselves out.
136
The way you avoid this is by actually starting to build something.
137
This way you can see the fruits of your labor
138
and you know for a fact that you're making progress and not burning yourself out.
139
So go to this repository,
140
click Python, and you'll see projects like web scraping,
141
web applications, bots, and even data science type projects.
142
And within them, it goes step by step on how to build these projects.
143
So even if you have no experience whatsoever,
144
you will build experience through that.
145
And the goal for you throughout each project should be thinking,
146
how can I take this tutorial and amp it up?
147
For example, maybe I don't want to create a Reddit bot,
148
but maybe I want to create a similar bot
149
that can actually scan the market and find the best time to buy a stock.
150
All of a sudden, you took this baseline project and transformed it to something that's actually impressive.
151
Then you can put it on your resume and actually use it to get hired.
152
But if you want to take it even a step above that and really showcase your depth of expertise in Python,
153
there's this GitHub repository right here called Build Your Own X.
154
Once again, it has so many advanced level project ideas for actually many different coding languages.
155
But if we just look at the Python one,
156
it shows you, for example,
157
how to create a Python interpreter.
158
And it gives you the framework to build bots,
159
to build databases, to build containers.
160
A lot of the work
161
that you do throughout these projects will set up the infrastructure for you to create startups or really cool apps one day.
162
And guess what?
163
Maybe you start working on this project because hopefully might get you a job.
164
But better yet, if you're able to create a startup through this,
165
you might be so successful that you don't even need a job.
166
And that's the type of mental framework that I want you to have.
167
Because with so many resources at your grasp,
168
you can literally do anything.
169
So by this point, you should be intermediate with Python.
170
You have your baseline and solid projects now.
171
But if you really want to accelerate your workflow,
172
we need to talk about the next layer,
173
which is actually the hippopotamus in the room, and that is AI.
174
A lot of people say that it might not be worth learning to code because of AI.
175
It might not be worth studying computer science.
176
This whole video might be useless because AI is going to take over.
177
Well, actually, Python is the best language to learn in this AI world.
178
Because a lot of machine learning,
179
AI development work and applications are run through Python.
180
Python has so many popular libraries like scikit-learn,
181
pandas, pytorch that actually help build machine learning models.
182
And actually being that expert in Python will actually give you a unique advantage in this AI world.
183
So how do you build that advantage?
184
Well two things.
185
Use AI as a partner and use AI as the product.
186
So on the partner front,
187
this means using a variety of different coding assistants to get your job done.
188
For example, Cursor is an IDE that I started using instead of VS Code
189
because it can scan through your whole code base and make code adjustments very quickly.
190
Then it'll actually generate files and files of Python code very quickly.
191
But if you're not there yet,
192
then GitHub Copilot is also great.
193
And I found this really useful for the scenario where you know how to solve the problem,
194
but you don't remember exactly,
195
oh, what was that function called again?
196
What was that type called again?
197
So this is kind of like your mini assistant to help you code faster.
198
Now, I want to be very, very clear.
199
I'm only recommending using AI once you have become an intermediate level in Python.
200
Because when you're still trying to learn the basics, it's not really good.
201
It's kind of like cheating on your homework.
202
You learn nothing.
203
But once you have the experience,
204
it will actually accelerate you so much further.
205
Just like no one learns to drive using a Lamborghini,
206
but once you have enough driving experience,
207
you can drive that car to accelerate your driving experience.
208
The second part of taking advantage of AI is using AI on the product standpoint.
209
You need to dive deep into the world of AI,
210
machine learning, and deep learning,
211
and start dabbling with Python libraries such as NumPy,
212
scikit-learn, and do some really cool projects.
213
One of my first ever real machine learning projects was creating a COVID-19 death predictor.
214
It was during the pandemic I gathered a bunch of data across a lot of different countries about their population sizes,
215
densities, and the impact of COVID-19.
216
Then I processed it using NumPy and plotted graphs using Matplotlib.
217
And so visually, we got to see a heat map of the impacts of the pandemic all across the world.
218
Plus, it was an excellent talking point on resumes and interviews.
219
And I actually used that to help me land the internships and jobs that I got afterwards.
220
But that was many, many years ago.
221
Nowadays, there's so much you can do with the power of AI, generative AI.
222
For example, you can create a chatbot that purchases items on Amazon.com.
223
So you don't have to go through the nitty gritties of finding a product,
224
adding your payment information and processing it.
225
Or you can create a machine learning recommendation system so that anytime you're in a new city,
226
you automatically get a text message of the best restaurants in your area that are tailored to your taste buds.
227
But the bigger picture I really want you to think about is once you create those products,
228
package it, put it in an app,
229
throw it on the app store.
230
And I have seen people literally make millions of dollars doing such things.
231
Or a step below that,
232
throw that project onto your resume,
233
add it to your LinkedIn,
234
and use it to actually help yourself get tired.
235
Alright, so finally, we've made it to the top of the pyramid,
236
and at this point, you have effectively learned Python pretty well.
237
But the goal for you isn't to just learn to code,
238
but rather, continuous mastery.
239
Staying the master of Python coding.
240
Just like a lot of things in life,
241
your goal isn't to get married,
242
it is to stay married.
243
The goal isn't to get in shape,
244
it is to stay in shape.
245
It is to master that practice.
246
So that means there is a continuous effort that you need to put week in,
247
week out, day in, day out to stay at the top of your game,
248
especially with coding in Python.
249
So to do that, you should try the brain dump protocol.
250
Every night, once you're done coding, turn off your laptop.
251
Take out a piece of paper and pen and write down for five minutes.
252
What did you do that day?
253
What went wrong?
254
What went right?
255
And what is something that you learned?
256
And it might seem a little bizarre at first,
257
like why are we writing this down?
258
But there's actually a deeper purpose.
259
First, you actually bring yourself back to reality and put your thoughts together.
260
Second, it gives you a sense of accomplishment because you work so hard throughout the day.
261
Third, it tells you exactly what you need to tackle the next day.
262
And fourth, over time, you'll be able to stack up your progress
263
and see what used to bother you then actually became a highlight for today.
264
And it'll reinforce internally the idea of your mastery.
265
If you want to lose weight fast,
266
you track all your calories and keep a food diary.
267
Just like that, if you want to learn to code Python fast,
268
you better keep a coding diary to track your progress.
269
And beyond just this, anytime you do anything cool or remarkable,
270
post about it online.
271
One of my friends for his last two jobs never even had to apply.
272
Because anytime he did a cool coding project,
273
he would post about it on Twitter.
274
And hiring managers would reach out to him because they see the amazing work that he does.
275
So once again, with the power of Python,
276
with the power of AI,
277
and honestly, with the power of the internet,
278
you have so many golden opportunities.
279
Honestly, it's so exciting.
280
Well, that's about all I have in this video.
281
I really hope that you guys enjoyed it.

練習のコツ
このレッスンの内容に基づいて、shadow speechを通じて英語のスピーキングスキルを向上させるための方法を紹介します。特に、速度とトーンに注意しながら、以下の点を意識した練習を行いましょう。
- まずは動画を見ながら、発せられる英語のフレーズをよく聞き、意味を理解してください。
- その後、動画を何度も繰り返し再生し、発音やリズムを真似してみてください。これが英語スピーキング練習の基礎となります。
- 自分の声を録音し、実際に自分がどれだけ正確に復唱できているかを確認してみましょう。
- 事前に重要な語彙やフレーズをノートに書き出し、意識的に使用するよう心がけましょう。
「英語シャドーイング」を実践することで、言語の習得がより効率的になります。焦らず自分のペースで、ぜひ積極的に練習を続けてください。
シャドーイングとは？英語上達に効果的な理由
シャドーイング（Shadowing）は、もともとプロの通訳者養成プログラムで開発された言語学習法で、多言語習得者として知られるDr. Alexander Arguelles によって広く普及されました。方法はシンプルですが非常に効果的：ネイティブスピーカーの英語を聞きながら、1〜2秒の遅延で声に出してすぐに繰り返す——まるで「影（shadow）」のように話者を追いかけます。文法ドリルや受動的なリスニングと異なり、シャドーイングは脳と口の筋肉が同時にリアルタイムで英語を処理・再現することを強制します。研究により、発音精度、抑揚、リズム、連音、リスニング力、そして会話の流暢さが大幅に向上することが確認されています。IELTSスピーキング対策や自然な英語コミュニケーションを目指す方に特におすすめです。
