导语：
本文主要介绍了关于python循环结构中的else怎么使用的相关知识，希望可以帮到处于编程学习途中的小伙伴
当执行循环组合中的else时，循环正常结束（即不使用break退出）。如以下代码：
numbers= [1,2,3,4,5]
for nin numbers:
if (n >5):
print('the value is %d '%(n))
break
else:
print('the for loop does not end with break')
i= 0
while(numbers[i] <5):
print('the index %d value is %d'%(i, numbers[i]))
if (numbers[i] <0) :
break
i= i+ 1
else:
print('the loop does not end with break')
numbers= [1,2,3,4,5]
for nin numbers:
if (n >5):
print('the value is %d '%(n))
break
else:
print('the for loop does not end with break')
i= 0
while(numbers[i] <5):
print('the index %d value is %d'%(i, numbers[i]))
if (numbers[i] <0) :
break
i= i+ 1
else:
print('the loop does not end with break')执行结果如下：
C:\Python27>python.exe for_else.py
thefor loop doesnot end withbreak
the index0 valueis 1
the index1 valueis 2
the index2 valueis 3
the index3 valueis 4
the loop doesnot end withbreak本文为原创文章，版权归知行编程网所有，欢迎分享本文，转载请保留出处！
