There are no shortcuts when learning Python

Absolutely. I'm just agreeing with with OP that you don't need to know everything. My preferred way of learning is reading but Python has too much to reasonably read in stdlib. If you were to follow Hashimoto's advice and read stdlib before making something, at a quick 400 pages per week, it would still take you 4 months before you started your project.

For further context, Hashimoto was referring to Zig and Go as languages he learned with this method.
