Python Built-in Functions
Common Python built-in functions: map, filter, zip, enumerate, sorted, isinstance with descriptions, categories, and usage examples.
Python built-in functions grouped by purpose, from map and filter to zip, enumerate, sorted and isinstance, with the common everyday builtins added: len, range, sum, min, max, any, all, abs, round, reversed, type, getattr, hasattr, iter, next and others.
Use it when
- You need the right built-in for a task and a one-line description.
- You are teaching Python's core vocabulary.
Watch out for
- Listed here are Python 3 built-ins; Python 2 differs (for example print and xrange).
- The official documentation lists all built-ins; this dataset covers the most used.
