For循环迭代2的幂 [英] For loop iterate over powers of 2

问题描述

我想编写一个for循环，该循环将为每个循环迭代2的幂.

I want to write a for loop that will iterate over the powers of 2 for each loop.

例如，我想要一个这样的范围:

For example I would want a range like this:

2, 4, 8, 16, ... , 1024

我该怎么办?

推荐答案

counter = 2

while counter <= 1024:
    print counter
    counter *= 2
