从列表中的值中删除多余的空间 [英] Delete Extra Space from Values In List

问题描述

我在Python中有一个数字列表，所有数字都在前面加了一个空格.如何删除多余的空间(以便仅保留数字)?下面是一个简短的示例(请注意多余的空格):

I have a list of numbers in Python all with a extra space in the front. How do I remove the extra space (so that only the numbers are left)? A short example is below (note the extra space):

List = [' 5432', ' 23421', ' 43242', .......]

推荐答案

使用 str.lstrip ，因为空格仅位于前面:

Use str.lstrip here, as the white-space is only at the front:

List = [s.lstrip() for s in List]
# ['5432', '23421', '43242', ...]

或者在这种情况下，看到您知道有多少个空间就可以做:

Or in this case, seeing as you know how many spaces there are you can just do:

List = [s[1:] for s in List]
