We're back after a server migration that caused effbot.org to fall over a bit harder than expected. Expect some glitches.

str.lstrip

lstrip([chars])

Return a copy of the string with leading characters removed. The chars argument is a string specifying the set of characters to be removed. If omitted or None, the chars argument defaults to removing whitespace. The chars argument is not a prefix; rather, all combinations of its values are stripped:

    >>> '   spacious   '.lstrip()
    'spacious   '
    >>> 'www.example.com'.lstrip('cmowz.')
    'example.com'

Changed in version 2.2.2: Support for the chars argument.
