python退出两层for循环
时间: 2023-08-08 17:09:12 浏览: 112
在Python中,要退出两层for循环,可以使用break语句。当满足退出条件时,使用break语句可以立即终止当前循环,并跳出最外层的循环。在这种情况下,else语句将不会执行。以下是一个示例代码:
```python
for i in range(5):
for j in range(5):
if i == 3 and j == 3:
break
else:
continue
break
```
在这个例子中,当i等于3且j等于3时,使用break语句退出内层循环。然后,外层循环的else语句中的continue语句将对外层循环起作用,跳过剩余的内层循环。最后,使用break语句退出外层循环,从而实现退出两层for循环的目的。
