Answer 1

Whitespace on both sides:

(两侧的空格：)

s = "   a string example  "
s = s.strip()

Whitespace on the right side:

(右侧的空格：)

s = s.rstrip()

Whitespace on the left side:

(左侧的空白：)

s = s.lstrip()

As thedz points out, you can provide an argument to strip arbitrary characters to any of these functions like this:

(正如thedz所指出的，您可以提供一个参数来将任意字符剥离到以下任何函数中，如下所示：)

s = s.strip(' 

')

This will strip any space, \t , \n , or \r characters from the left-hand side, right-hand side, or both sides of the string.

(这将从字符串的左侧，右侧或两侧去除所有空格， \t ， \n或\r字符。)

The examples above only remove strings from the left-hand and right-hand sides of strings.

(上面的示例仅从字符串的左侧和右侧删除字符串。)

If you want to also remove characters from the middle of a string, try re.sub :

(如果您还想从字符串中间删除字符，请尝试re.sub ：)

import re
print re.sub('[s+]', '', s)

That should print out:

(那应该打印出来：)
