Example: Breaking while loop Copy num = 0 while num < 5: num += 1 # num += 1 is same as num = num + 1 print('num = ', num) if num == 3: # condition before exiting a loop break Try it Output num = 1 num = 2 num = 3 ...
As you can notice in an example above, there is an if-else condition inside the while loop which enables you to introduce further conditions in your code. Hold on! This is not the only way that you can customize your loop. You can also include some more while loop inside you existing ...
对于while循环,else子句的行为是类似的: i =0whilei <5: i +=1ifi ==3:breakelse:print("Loop completed without breaking")# 因为循环在i等于3时通过break中断,所以不会输出这句话 在这个while循环的例子中,因为循环通过break语句在i等于3时提前退出,所以else子句中的代码块不会被执行。
只要输入的第一个字符是 e 字符,如果你仅仅想跳到下一个迭代,而不是跳出While循环,那该怎么办呢? 英文:As long as the first charater of whatever is input, is the e character, What if you only want to skip to the next iteration, instead of breaking out of the while loop. ...
