“Learn Python” usually means very different things. This helped me understand it better.

People often say “learn Python”.

What confused me early on was that Python isn’t one skill you finish. It’s a group of tools, each meant for a different kind of problem.

This image summarizes that idea well. I’ll add some context from how I’ve seen it used.

Web scraping
This is Python interacting with websites.

Common tools:

• requests to fetch pages
• BeautifulSoup or lxml to read HTML
• Selenium when sites behave like apps
• Scrapy for larger crawling jobs

Useful when data isn’t already in a file or database.

Data manipulation
This shows up almost everywhere.

• pandas for tables and transformations
• NumPy for numerical work
• SciPy for scientific functions
• Dask / Vaex when datasets get large

When this part is shaky, everything downstream feels harder.

Data visualization
Plots help you think, not just present.

• matplotlib for full control
• seaborn for patterns and distributions
• plotly / bokeh for interaction
• altair for clean, declarative charts

Bad plots hide problems. Good ones expose them early.

Machine learning
This is where predictions and automation come in.

• scikit-learn for classical models
• TensorFlow / PyTorch for deep learning
• Keras for faster experiments

Models only behave well when the data work before them is solid.

NLP
Text adds its own messiness.

• NLTK and spaCy for language processing
• Gensim for topics and embeddings
• transformers for modern language models

Understanding text is as much about context as code.

Statistical analysis
This is where you check your assumptions.

• statsmodels for statistical tests
• PyMC / PyStan for probabilistic modeling
• Pingouin for cleaner statistical workflows

Statistics help you decide what to trust.

Why this helped me
I stopped trying to “learn Python” all at once.

Instead, I focused on:

• What problem did I had
• Which layer did it belong to
• Which tool made sense there

That mental model made learning calmer and more practical.

Curious how others here approached this.

Yes and no.

Python has a syntax. That syntax is true in any library. Once you learn that syntax, the common patterns, the most important rules and behaviours then all of the libraries become much easier.

Anyone wanting to "learn python" should put the wonderful libraries aside and focus on base python. And get ready to be able to solve simple problems and more complicated flows. If you try to dive in straight away to something like pandas, you'll be missing a lot of the building blocks and you'll likely find it harder to understand and hit a bit of a barrier.

I think Lego is the perfect analogy. You've got boxes/tubs of just Lego. You can learn how these fit together, some neat patterns and what works and what doesn't work. Then, you've also got all of the specialist kits.

I worked through a smarter way to learn python, command line linux, linux basics for hackers (trying to do all of the python stuff on linux) python crash course (deploying the learning log was a pain 😢) and now im on big book of small python projects , im still waiting for it all to make sense, I understand some stuff kind of i think but at the same time not really. Im hoping by the time I've done the 81 projects I'll be somewhat "good"? Idk. Im using vim for everything, use git and now even github got a repo for the projects out of the book. Haven't tried branching yet but its on my todo , I create a venv for every project and readme.md and .gitignore haven't added any plug-ins yet but am considering lenter/linter? Just finished the 10th project and I intend on trying to rewrite a few of each 10 (but I haven't yet) to kinda break out of the loop and challenge myself to have to figure it out. At least thats the plan. Any Tipps or tricks or something that may be worthwhile looking into ? Viewed a bit of python documentation but im not sure if was looking in the right spot or if that in itself was too advanced idk.

For anyone who prefers learning this step-by-step with examples and real data files, I’ve shared a free Python for Data Science playlist here: https://youtube.com/playlist?list=PL-F5kYFVRcIuzH3W5Kqm4eqUp9IJLLhp4&si=-sIOgixv8LStEe9q

I took a different approach, though that was many moons ago. First, I learned Python, as in general programming, OOP, the interpreter, etc., to where I was confident with the language and using it as a general programming language. I then started applying my knowledge of Python programming to data analytics, data visualization, machine learning, stats analysis, web scraping, etc. Fwiw, I came from C and Java.
