Add snake_case version of camelCase methods to classes

Camel Case Class Fixer.py

import re

camel_re = re.compile(r'([a-z]+[A-Z])+[a-z]+')

def fix_camel_case(camel_class):
    for camel_attr in dir(camel_class):
        if camel_re.match(camel_attr):
            snake_attr = ''.join(char if char.islower() or char.isdigit() else "_%s" % char.lower() 
                                 for char in camel_attr)
            setattr(camel_class, snake_attr, getattr(camel_class, camel_attr))

Or the "shorter = better" version:

import re 

fix_camel_case = lambda camel_class: [setattr(camel_class, ''.join(char if char.islower() or char.isdigit() else "_%s" % char.lower() for char in camel_attr), getattr(camel_class, camel_attr)) for camel_attr in dir(camel_class) if re.match(r'([a-z0-9]+[A-Z])+[a-z0-9]+', camel_attr)]
