Purpose

Returns a string with no leading or trailing spaces.

Method

You can use the following methods of string processing:

String. lstrip (s [, chars])

Return a copy of the string with leading characters removed. if chars is omitted or None, whitespace characters are removed. if given and not None, chars must be a string; the characters in the string will be stripped from the beginning of the string this method is called on.

String. rstrip (s [, chars])

Return a copy of the string with trailing characters removed. if chars is omitted or None, whitespace characters are removed. if given and not None, chars must be a string; the characters in the string will be stripped from the end of the string this method is called on.

String. strip (s [, chars])

Return a copy of the string with leading and trailing characters removed. if chars is omitted or None, whitespace characters are removed. if given and not None, chars must be a string; the characters in the string will be stripped from the both ends of the string this method is called on.

The specific effect is as follows:

The Code is as follows:

In [10]: x = 'Hi, Jack! '

In [11]: print '|', x. lstrip (), '|', x. rstrip (), '|', x. strip (), '|'

| Hi, Jack! | Hi, Jack! | Hi, Jack! |

The chars parameter is used to delete a specific symbol. Note that spaces are not removed. For example:

The Code is as follows:

In [12]: x = 'xyxyxxxyy Hello xyxyxyxyy'

In [13]: print x. strip ('xy ')

Hello
