python 作用域

每日总结

if 1 == 1:
    name = "aid"
print(name)
for i in range(10):
    age = i
print(age) 

def aid():
    a='ai1807'
print(a)

def aid():
   a='ai1807'
aid()
print(a)

name = "aid"
def f1():
    name = "hcw"
    def f2():
        name = "dl"
        print(name)
    f2()
f1()
#Python中有作用域链，变量会由内到外找，先去自己作用域去找，自己没有再去上级去找，直到找不到报错

a=1
def f2():
    print(a)
def f1():
    a=2
    f2()
f1()

a=1
def f1():
    a=2
    def f2():
        print(a)
    return f2
test=f1()
test()
