Three methods are provided that offer the ability to strip leading and trailing characters from a string:
str.lstrip. All three methods have the same signature and all three return a new string object with unwanted characters removed.
str.strip acts on a given string and removes (strips) any leading or trailing characters contained in the argument
chars is not supplied or is
None, all white space characters are removed by default. For example:
>>> " a line with leading and trailing space ".strip() 'a line with leading and trailing space'
chars is supplied, all characters contained in it are removed from the string, which is returned. For example:
>>> ">>> a Python prompt".strip('> ') # strips '>' character and space character 'a Python prompt'
These methods have similar semantics and arguments with
str.strip(), their difference lies in the direction from which they start.
str.rstrip() starts from the end of the string while
str.lstrip() splits from the start of the string.
For example, using
>>> " spacious string ".rstrip() ' spacious string'
>>> " spacious string ".rstrip() 'spacious string '
