这应该是Python独有的特性吧,循环也可以有else。当循环正常结束(没有break)后,就会执行else代码段: for i in range(3): print(i) else: print('loop ends') for i in range(3): if i > 1: break print(i) else: print('loop ends')

Generating a numerical loop variable with the range() function For loops are normally used in Python to iterate over the elements in a collection. They usually aren’t used to increment an integer. The best way to do this is to create a range object using the range() function and iterat...
