Global School #函数内修改全局变量
School = "Wo de"
#name = ' Li ' #这个函数就是这个变量的作用域
# print (name)
Name= ' Alx '
Change (name)
Print ("hhh%s"%school)


#在函数里改一个局部变量, the function is called and there is no way to know where the variable was changed.
# Back and forth calls can cause confusion in function logic, only a global variable outside is still viable

   #字符串与单独的整数不能在函数中 Modified values, lists, dictionaries, collections, classes, etc. this complex data can be changed within the function
