decapitalize

Decapitalizes the first letter of a string.

Decapitalizes the fist letter of the sring and then adds it with rest of the string. Omit the upper_rest parameter to keep the rest of the string intact, or set it to true to convert to uppercase.

def decapitalize(string, upper_rest=False):
    return str[:1].lower() + (str[1:].upper() if upper_rest else str[1:])

decapitalize('FooBar') # 'fooBar'
decapitalize('FooBar', True) # 'fOOBAR'
