How does strip works in python?

Question

I want to know how does rstrip and lstrip works in python. Say, if I have a string

>> a = \'thisthat\'
>> a.rstrip(\'hat\')
out : \'this\'
>&g         


        

Answer 1

lstrip, rstrip and strip remove characters from the left, right and both ends of a string respectively. By default they remove whitespace characters (space, tabs, linebreaks, etc)

>>> a = '  string with spaces  '
>>> a.strip()
'string with spaces'
>>> a.lstrip()
'string with spaces  '
>>> a.rstrip()
'  string with spaces'

You can use the chars parameter to change the characters it strips.

>>> a = '....string....'
>>> a.strip('.')
'string'

However, based on your question it sounds like you are actually looking for replace

>>> a = 'thisthat'
>>> a.replace('hat', '')
'thist'
>>> a.replace('this', '')
'that'
