如何使用while循环打印2到100的偶数? [英] How is it possible to use a while loop to print even numbers 2 through 100?

问题描述

我是一个初学者，因此我陷入了这个问题，编写一个使用while循环打印2到100的偶数的python代码.提示ConsecutiveEven相差2."

I am a beginner and I am stuck on this problem, "Write a python code that uses a while loop to print even numbers from 2 through 100. Hint ConsecutiveEven differ by 2."

这是我到目前为止想出的:

Here is what I came up with so far:

 while num in range(22,101,2):
              print(num)

推荐答案

使用for和range()或使用while并显式增加数字.例如:

Use either for with range(), or use while and explicitly increment the number. For example:

>>> i = 2
>>> while i <=10: # Using while
...    print(i)
...    i += 2
...
2
4
6
8
10

>>> for i in range(2, 11, 2): # Using for
...    print(i)
...
2
4
6
8
10
