Thanks for bottom posting and trimming, but you should leave some content quoted for context. Otherwise people will not what you are referring to. You can find answers to questions like this in the API. http://docs.python.org/2/library/stdtypes.html#str.lower I would recommend taking time to get familiar with the Athena interpreter. It can also answer questions like this (but with less detail than the web API). You can use dir() to find the attributes on any object. help() will give you docstring for the attribute/class. >>> 'A'.lower() 'a' >>> help(''.lower) Help on built-in function lower: lower(...) S.lower() -> string Return a copy of the string S converted to lowercase. >>> help(dir) Help on built-in function dir in module __builtin__: dir(...) dir([object]) -> list of strings If called without an argument, return the names in the current scope. Else, return an alphabetized list of names comprising (some of) the attributes of the given object, and of attributes reachable from it. If the object supplies a method named __dir__, it will be used; otherwise the default dir() logic is used and returns: for a module object: the module's attributes. for a class object: its attributes, and recursively the attributes of its bases. for any other object: its attributes, its class's attributes, and recursively the attributes of its class's base classes. >>> dir('') ['__add__', '__class__', '__contains__', '__delattr__', '__doc__', '__eq__', '__format__', '__ge__', '__getattribute__', '__getitem_\ _', '__getnewargs__', '__getslice__', '__gt__', '__hash__', '__init__', '__le__', '__len__', '__lt__', '__mod__', '__mul__', '__ne__\ ', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__rmod__', '__rmul__', '__setattr__', '__sizeof__', '__str__', '__subclass\ hook__', '_formatter_field_name_split', '_formatter_parser', 'capitalize', 'center', 'count', 'decode', 'encode', 'endswith', 'expan\ dtabs', 'find', 'format', 'index', 'isalnum', 'isalpha', 'isdigit', 'islower', 'isspace', 'istitle', 'isupper', 'join', 'ljust', 'lo\ wer', 'lstrip', 'partition', 'replace', 'rfind', 'rindex', 'rjust', 'rpartition', 'rsplit', 'rstrip', 'split', 'splitlines', 'starts\ with', 'strip', 'swapcase', 'title', 'translate', 'upper', 'zfill'] If you want to see all the relevant information you can use help() on the class [e.g. help(str)]. I think help(class) will not show functions that start with _ unless they are python magic dunder functions (e.g. __str__). ~Ramit This email is confidential and subject to important disclaimers and conditions including on offers for the purchase or sale of securities, accuracy and completeness of information, viruses, confidentiality, legal privilege, and legal entity disclaimers, available at http://www.jpmorgan.com/pages/disclosures/email. -- https://mail.python.org/mailman/listinfo/python-list
