They don't; it's purely a matter of convention that Python style guides prefer under_scored over camelCased. But you are entirely free to implement all of your python functions and variables and whatnot in camelCase, and in fact, many libraries do.
- peller 14y agoYou could probably even try to write a decorator that converted under_scores function names to camelCase for a nice little introduction into various parts of some of the more internal pieces of python.
- _ZeD_ 14y agouhmm, AFAIK pep8 suggest UpperCamelCase for classes, under_score for packages, methods and functions[0] btw: it's not a decorator :) but a camelCase->under_score renamer it's pretty easy to write import re def unCamel(obj, *maybe_camels): if not maybe_camels: maybe_camels = filter(lambda n: not n.startswith('_'), dir(obj)) for maybe_camel in maybe_camels: underscore = re.sub(r'([^A-Z])([A-Z])([^A-Z])', lambda m: '%c_%c%c' % (m.group(1), m.group(2).lower(), m.group(3)), maybe_camel) if underscore != maybe_camel: setattr(obj, underscore, getattr(obj, maybe_camel)) if __name__ == '__main__': class CamelCase(object): def multiWordMethod(self): print('called multiWordMethod') def multiWordFunction(): print('called multiWordFunction') unCamel(CamelCase) # magic import sys unCamel(sys.modules[__name__], 'multiWordFunction') # magic CamelCase().multi_word_method() multi_word_function() [0] http://www.python.org/dev/peps/pep-0008/ http://www.python.org/dev/peps/pep-0008/
- cnlwsu 14y agoEven in python standard library there are mixtures ie threading.Thread. Although those (as I understand it) are just remnants of old implementation that is kept for backwards compatibility.
- aidos 14y agoIsn't that normal? I though lowercase module name, uppercase class was the standard casing. threading.Thread would seem to be consistent with the Google Python Style Guide (threading = module, Thread = Class) http://google-styleguide.googlecode.com/svn/trunk/pyguide.html?showone=Naming#Naming http://google-styleguide.googlecode.com/svn/trunk/pyguide.ht...
- cnlwsu 14y agothe methods of threading.Thread are camel case (ie getName) http://docs.python.org/2/library/threading.html http://docs.python.org/2/library/threading.html
