Do people actually remember all the Python docs?

Looking things up is normal. You’ll gradually remember the parts you use often, but there’s no need to learn whole pages by heart. Keep the documentation nearby and use it while you work.

Try building small things rather than rereading documentation just to memorize it. When you need a function, look it up, use it, and come back to it later in another project. Repeated use is what makes the common bits stick.

I’d focus on knowing how to find the answer: search the relevant documentation, check the function’s parameters and return value, then test a tiny example. Remembering what a tool can do is often more useful than remembering its exact syntax.

If you keep looking up the same few things, make a small searchable note with examples that make sense to you. Don’t try to summarize everything. For the less familiar stuff, the official docs are still a perfectly good reference.
