11th function and functional programming

A call function

1 keyword Parameters

def foo (x):
Foo_suite # Presumably does some processing with ' X '

Standard call Foo (): foo (' Bar ') foo (y)

The keyword calls foo (): foo (x=42) foo (x= ' bar ') foo (x=y) that explicitly gives the corresponding parameter name

2 parameter Groups

Python allows programmers to execute a function that does not explicitly define parameters by passing a tuple (non-keyword argument) or dictionary (keyword argument) as a parameter group to the function.

　　

Two create functions

Three function parameters

Four-function programming

Five variable scopes

Six generators
