for循环中的计数器和重置计数器

Question

我有以下代码：

for i in range(10):
    while True:
       num = int(input("Enter an integer: "))
       print("The double of",num,"is",2 * num)
    print('10')

我想做的是在 10 次迭代后，消息应该打印 10。它只打印一次，我如何重置计数器以便它在达到 10 后再次开始？

我想让程序做的是在 10 次迭代后打印“10”，但循环是无限的，所以它永远不会中断。

您可以使用它，您只需循环一次并检查计数器是否可以被 10 整除以打印消息

for i in range(1, 100):
    num = int(input("Enter an integer: "))
    print("The double of",num,"is",2 * num)
    if i%10==0:
        print('10')

如果你想要无限循环：

i = 1
while True:
    num = int(input("Enter an integer: "))
    print("The double of",num,"is",2 * num)
    if i%10==0:
        print('10')
    i+=1

for i in range(1,21) 的结果将是

The double of 50 is 100
The double of 50 is 100
The double of 50 is 100
The double of 50 is 100
The double of 50 is 100
The double of 50 is 100
The double of 50 is 100
The double of 50 is 100
The double of 50 is 100
The double of 50 is 100
10
The double of 50 is 100
The double of 50 is 100
The double of 50 is 100
The double of 50 is 100
The double of 50 is 100
The double of 50 is 100
The double of 50 is 100
The double of 50 is 100
The double of 50 is 100
The double of 50 is 100
10
