Python: Local variables and global variables

#!usr/bin/env python
#-*-Coding:utf-8-*-
#除了字符串和整数, the other can be modified in the function
#在子程序中定义的变量称为局部变量, a variable defined at the beginning of a program is called a global variable
#全局变量作用域是整个程序, and the local variable scope is the subroutine that defines the variable

__author__ = "Samson"
School = "Oldboy"
def change_name (name):
    Global school# is defined as a globals, and the school is the same as the fifth row school
    School = "Edu"
    Print ("Before changed", name)
    Name = Name.title () #这个函数就是这个变量的作用域 (local variable)
    Print ("After changed", name)

Name = "Samson"
Change_name (name)
Print (name)

names = ["Alex", "Samson"]
def change ():
    Names[0] = "Sam"
