As you can see, you start off the loop with the for keyword. Next, you make use of a variables index and languages, the in keyword, and the range() function to create a sequence of numbers. Additionally, you see that you also use the len() function in this case, as the languages...
您需要执行in_box=str(in_box): from random import randrange in_box = randrange(1, 5) in_box = str(in_box) guess_box = False print("To guess which box enter in the numbers that each box relates to, eg, Box 1 will be the number 1! Ready? Set? Go!") while guess_box != in_...
Using awhileloop enables Python to keep running through our code, adding one tonumbereach time. Whenever we find a multiple, it gets appended tomultiple_list. The secondifstatement then checks to see if we've hit ten multiples, usingbreakto exit the loop when this condition is satisfied. ...
As long as we enter positive numbers, the loop adds them up and prompts us to enter more numbers. If we enter a negative number, the loop terminates without adding the negative number. More on JavaScript while and do...while Loops What is an infinite while loop in JavaScript? An infi...

+= 1 else:print("账户已锁定")这里结合了else子句，当循环正常结束（非break退出）时触发锁定提示。这种结构适合处理需要限制尝试次数的场景。与break和continue配合能实现更灵活的控制。假设要过滤掉列表中的负数：numbers = [3, -1, 4, -5, 7]filtered = []index = 0 while index < len(numbers):
