What are Python's built-in functions?

Python has many useful built-in functions that require no import. Numeric: abs(), round(), pow(), divmod(), sum(), min(), max(). Type conversion: int(), float(), str(), bool(), list(), tuple(), dict(), set(). Introspection: type(), isinstance(), issubclass(), dir(), vars(), id(), callable(). Iteration: range(), enumerate() (index + value pairs), zip() (combine iterables), map(), filter(), sorted(), reversed(), next(), iter(), len(). I/O: print(), input(), open(). Functional: any(), all(), hash(). Code: eval(), exec(), compile().
