python函数嵌套函数
def func():
print("helloworld")
global func1
def func1():
print("hello world")
func()
func1()
执行:
hello helo
Traceback (most recent call last):
File "C:\Users\Administrator\Desktop\ibm\myfile2.py", line 8, in <module>
func1()
NameError: name 'func1' is not defined
[Finished in 0.2s]
解决思路1:提前声明
def func1():
pass
def func():
print("hello helo")
global func1
def func1():
print("heloworld")
func()
func1()
解决思路2:作为返回值
def func():
print("hello helo")
def func1():
print("heloworld")
return func1
myfun=func()
myfun()
