Welcome to Python for Everybody. This course teaches you to program in Python 3 even if you have never written a line of code. You start with the big picture: why people learn to program, how a computer’s CPU, memory, and storage work together, and how Python fits in as a language you can read and write.
From there you build the core skills step by step. You learn variables, expressions, and statements so you can store data and do calculations. You use conditional execution so programs can make decisions, and you practice loops so you can repeat work over data. You learn functions—the “store and reuse” pattern—so you can organize code into pieces you call when you need them.
Then the course moves into text and real data. You work with strings, open and read files, and process lines of text. You learn Python’s main collections for holding many values: lists, dictionaries, and tuples. You use dictionaries to count things (histograms), and tuples to sort data effectively. Finally, you get an introduction to regular expressions so you can search for patterns and extract information from text with the `re` library. You can think of regular expressions as a second (very small) programming language for you to learn.
