Python functions, classes

The rules that define a function are described in the

• The function code block begins with a def keyword followed by the function identifier name and parentheses ().
• Any incoming parameters and arguments must be placed in the middle of the parentheses. Parentheses can be used to define parameters.
• The first line of the function statement can optionally use the document string-for storing the function description.
• The function contents begin with a colon and are indented.
• Return[expression] End Function, optionally returning a value to the caller. Return without an expression is equivalent to returning None.

def name (name): Print name

function calls are called directly by the functions name, that is, name (value)

Class

A class is an abstraction of an instance, and an instance is an implementation of a class, and the relationship is like a car and a BMW X5, one is the whole concept, the other is a real thing.

To define a class:

CALSS name (self,name):    def __init__ (Self,name,sex)
Self_name = ' Kang '    self_sex = ' sex '    print name

You can define the class's properties (name, Sex) and Method (__init__) directly when defining the class.
