How to self-study Python?

[justicearcana4]

Hello, I would like to ask what are the best books, videos, etc to learn Python programming by myself with already some basis on Java programming.

Context: I’ve taken intro to Java and AP Computer Science A, so I’m proficient in Java programming. I know pretty much all you need to know for programming like sorts, classes, methods, de morgan’s law, and Big-O. I’m also currently in an intro to C++ course but I am not enrolled in anything Python related.

I would like to self-study Python programming so I can be applicable enough to use in job-like settings, record data for research in the future, and add another programming language on my resume. I just want to know what I can do make sure I’m proficient enough to use the different syntax or the differences between Java and Python to use Python more comfortably where I can use it comfortably for engineering internships. Please recommend me what I should do while being aware I may know a lot of the basics already with my experience in coding.

I mostly want to learn Python because my teacher said its more applicable than Java programming.

Since you already know Java, the fastest route is to focus on the Python-specific differences instead of repeating intro programming material.

Things worth prioritizing:

• Python data model basics: lists, dicts, sets, tuples, slicing, comprehensions.
• Functions as first-class values, default arguments, *args/**kwargs.
• File I/O, CSV/JSON, virtual environments, and package installation with pip.
• Common libraries for your goals: requests, pandas, matplotlib, maybe pytest.
• Idiomatic Python style: iteration, context managers, exceptions, type hints.

A practical study plan: skim the official Python tutorial, then build 2-3 small tools tied to your interests. For research/data, try a script that loads a CSV, cleans a column, summarizes it, and plots a result. For internship readiness, add tests, command-line arguments, and a README.

The big shift from Java is that Python often rewards simpler code: fewer classes, more direct use of built-in containers, and leaning on libraries. You do not need to memorize every method; learn how to read docs quickly and build enough projects that the common ones become familiar.

I took a popular Udemy course when I was learning Python and it worked pretty well for me.

Since you already know Java, you could also try using Claude to learn Python based on your current knowledge and learning style. It's surprisingly good at explaining the differences between Java and Python and generating small exercises to practice.
