If you are not being a troll, there are two easy ways to answer such a 
question.

 >>> dir('')
['__add__', '__class__', '__contains__', '__delattr__', '__doc__', 
'__eq__', '__format__', '__ge__', '__getattribute__', '__getitem__', 
'__getnewargs__', '__gt__', '__hash__', '__init__', '__iter__', 
'__le__', '__len__', '__lt__', '__mod__', '__mul__', '__ne__', 
'__new__', '__reduce__', '__reduce_ex__', '__repr__', '__rmod__', 
'__rmul__', '__setattr__', '__sizeof__', '__str__', '__subclasshook__', 
'_formatter_field_name_split', '_formatter_parser', 'capitalize', 
'center', 'count', 'encode', 'endswith', 'expandtabs', 'find', 'format', 
'index', 'isalnum', 'isalpha', 'isdecimal', 'isdigit', 'isidentifier', 
'islower', 'isnumeric', 'isprintable', 'isspace', 'istitle', 'isupper', 
'join', 'ljust', 'lower', 'lstrip', 'maketrans', 'partition', 'replace', 
'rfind', 'rindex', 'rjust', 'rpartition', 'rsplit', 'rstrip', 'split', 
'splitlines', 'startswith', 'strip', 'swapcase', 'title', 'translate', 
'upper', 'zfill']

followed by
 >>> help(''.lower)
Help on built-in function lower:
lower(...)
     S.lower() -> str
     Return a copy of the string S converted to lowercase.

OR
 >>> help(str)
which gives screenfuls of info including the above.
