It's important to know that these numbers will vary based on what you're measuring, your hardware architecture, and how your particular Python binary was built.

For example, my M4 Max running Python 3.14.2 from Homebrew (built, not poured) takes 19.73MB of RAM to launch the REPL (running `python3` at a prompt).

The same Python version launched on the same system with a single invocation for `time.sleep()`[1] takes 11.70MB.

My Intel Mac running Python 3.14.2 from Homebrew (poured) takes 37.22MB of RAM to launch the REPL and 9.48MB for `time.sleep`.

My number for "how much memory it's using" comes from running `ps auxw | grep python`, taking the value of the resident set size (RSS column), and dividing by 1,024.

1: python3 -c 'from time import sleep; sleep(100)'
