Quick Answer
Python functions are first-class objects - assignable to variables, passable as arguments, returnable from other functions. def defines a function, lambda creates anonymous single-expression functions. Default parameter values, *args (variable positional args), **kwargs (variable keyword args). Closures capture variables from enclosing scope. Nested functions, decorators, and higher-order functions are all supported.
