foriinrange(3):print(i)else:print('loop ends')foriinrange(3):ifi>1:breakprint(i)else:print('loop ends') 猜猜这段代码的输出吧,如果没有把握就亲自执行一下就明白了。 总结 循环是程序中另外一种重要的流程控制,在批量处理数据、服务器程序中大量使用。
You can observe that initially ‘i’ value is initialized to 0 i.e equal to the start parameter value and stop parameter value is equal to increment value inside the while loop. 3. Conclusion We have seen how to use the Python range() in the while loop by considering three different sce...
is True,the indented block of codes will be executed and the loop will continue its iteration. The indented block of codes prints out the count and then increment the count by 1. Then it loops back to check for the while condition again. Once the condition becomes False, the loop ends....
在Python底层,True和False其实是1和0,所以如果我们执行以下操作,是不会报错的,但是在逻辑上毫无意义。 # True and False are actually 1 and 0 but with different keywords True + True # => 2 True * 8 # => 8 False - 5 # => -5 我们用==判断相等的操作,可以看出来True==1, False == 0. ...
