Let’s say you need to accept user input but without the white spaces. The strip() method of the string object can be used to delete any white space characters from a string.

>>> s1 = ' Whitespace '
>>> s1
' Whitespace '
>>> s2 = s1.strip()
>>> s2
'Whitespace'

The strip() method gets rid of any white space at the beginning and the end of a string.
You can strip unwanted white space only at the beginning or only at the end of a string.

>>> s1 = ' Whitespace '
>>> s2 = s1.lstrip()
>>> s2
'Whitespace '
>>> s3 = s1.rstrip()
>>> s3
' Whitespace'
