.py. Nothing magic. A .py file is a to‑do list for the interpreter.That's it. Language (Python, the rules) vs. program (your .py, the instructions) vs. interpreter (the thing that runs them) vs. CLI (where you stand to run them).
You don't need to memorize these. You need to run them.
python --version # ask Python which version is installed
python3 --version # the same question on macOS/Linux
python # start the interpreter (the REPL)
exit() # leave the interpreter, stay in the terminalThe REPL is worth naming. It stands for Read–Eval–Print–Loop: it Reads a line you type, Evaluates it, Prints the result, and Loops back for more. It's Python talking back in real time — the fastest way to test an idea.
