Third-party libraries are the core strength of Python’s ecosystem. Standard libraries come with the installation, while third-party libraries are installed via pip, all accessed using import statements.

How to Learn

You don’t need to memorize every library — just master the commonly-used ones (numpy, pandas for data; re, BeautifulSoup for extraction). For others, read the official docs once to understand what they can do, and refer back to your notes when needed.
Libraries are like bricks for building a house — do you need to understand their material composition? Just learn to use them.
Official documentation is the most authoritative source. Blog tutorials can supplement, but should not be your primary reference.
