python基础7：全局变量和局部变量

先找本地变量，再找全局变量

 

改变全局变量：

 1 name = "A"
 2 def d1():
 3     name = "B"
 4     def d11():
 5         nonlocal name
 6         name = "C"
 7     d11()
 8     print(name)
 9 
10 print(name)
11 d1()
12 print(name)
#输出结果：
\'\'\'
A
C
A
\'\'\'

 

改变本地变量：

 1 name = "A"
 2 def d1():
 3     name = "B"
 4     def d11():
 5         global name
 6         name = "C"
 7     d11()
 8     print(name)
 9 
10 print(name)
11 d1()
12 print(name)

#输出结果：
\'\'\'
A
B
C
\'\'\'
