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')

我想要做的是在 10 次迭代后，消息应该打印 10。它这样做但只有一次，我如何重置计数器以便在达到 10 后重新开始？

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

Answer 1

您可以使用它，您只需循环一次并检查计数器是否可被 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

结果是for i in range(1,21)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

Answer 2

你可以这样做：

x = 0
for x in range(10):
     num = int(input("enter an integer: "))
     x += 1
     if x == 10:
         print("10")
         x = 0
     else:
         pass
