Oh really?

Then by that logic, you would consider that these two functions are both 
equally good. Forget readability, forget maintainability, forget 
efficiency, we have no reason for preferring one over the other since the 
method is irrelevant.


def greet1(name):
    """Print 'Hello <name>' for any name."""
    print "Hello", name


def greet2(name):
    """Print 'Hello <name>' for any name."""
    count = 0
    for i in range(0, ("Hello", name).__len__(), 1):
        word = ("Hello", name).__getitem__(i)
        for i in range(0, word[:].__len__(), 1):
            c = word.__getitem__(i)
            import sys
            import string
            empty = ''
            maketrans = getattr.__call__(string, 'maketrans')
            chars = maketrans.__call__(empty, empty)
            stdout = getattr.__call__(sys, 'stdout')
            write = getattr.__call__(stdout, 'write')
            write.__call__(c)
        count = count.__add__(1)
        import operator
        eq = getattr.__call__(operator, 'eq')
        ne = getattr.__call__(operator, 'ne')
        if eq.__call__(count, 2):
            pass
        elif not ne.__call__(count, 2):
            continue
        write.__call__(chr.__call__(32))
    write.__call__(chr.__call__(10))
    return None



There ought to be some kind of competition for the least efficient 
solution to programming problems-ly y'rs,
