所以想象一下,我想遍历一个从 0 到 100 的循环,但跳过奇数(所以两两").
So imagine I want to go over a loop from 0 to 100, but skipping the odd numbers (so going "two by two").
for x in range(0,100):
if x%2 == 0:
print x
这解决了它.但是想象一下我想跳两个数字吗?那么三个呢?没有办法吗?
This fixes it. But imagine I want to do so jumping two numbers? And what about three? Isn't there a way?
使用 step 参数(最后一个,可选):
Use the step argument (the last, optional):
for x in range(0, 100, 2):
print(x)
请注意,如果您真的想保留奇数,则变为:
Note that if you actually want to keep the odd numbers, it becomes:
for x in range(1, 100, 2):
print(x)
范围是一个非常 强大 功能.
