Scope of the Python module

Scope: variable, function

public (public): can be directly referenced, such as: ABC, PI, test (), similar to __xxx__ such a special variable. Lenovo : In the C language, when something in the module wants to be referenced externally, it is preceded by an extern, or it can be added without extern

private (Secret): should not be directly quoted, such as: _xxx/__xxx variables such as Lenovo: In C, when something in the module does not want to be referenced externally, the static

is added in front of it.

What do I do when there are variables or functions in a module that you do not want to be referenced by others? As follows:

Private.py is the modulated module

public.py is a public module

#private.py

#!/usr/bin/env Python3
#-*-Coding:utf-8-*-

def _private_1 (name):     #该函数为秘密函数

    return ' Hello,%s '% name

def _private_2 (name):    #该函数为秘密函数
    return ' Hi,%s '% name

def greeting (name= "):    #该函数为公开函数, can be called
    if Len (name) > 3:
   & nbsp;    return _private_1 (name)
    else:
         return _private_2 (name)

If __name__== ' __main__ ':
Print (greeting ())

#public. py

#!/usr/bin/env Python3
#-*-Coding:utf-8-*-

From private import greeting #导入private模块的greeting函数

Print (Greeting ([' You ', ' very ', ' nice '))
