Although on the flip side, Python's official web documentation is 100 
times better than Ruby's. All the semantics are documented, every single 
change to the language is documented.

My other pet peeve with ruby is the ludicrous way that Strings are 
handled in 1.9. Python 3's approach is clear, precisely defined, and 
symmetrical.

I can live with that, especially after having used HAML.

What I find annoying about Python is that methods are function values, 
and you have to remember to use () to call them. But this means you have 
to know whether an attribute is a direct value, or is an accessor method 
which returns the value you want.

e.g. is it str.len or str.len()  ?

Answer: neither, it's len(str). But that's actually a shortcut for 
str.__len__()

That would be simple enough, except that some objects can have 
'properties' which you access as if they were values, but are actually 
calling methods under the surface:

import random

class Foo(object):
    def __random(self):
        return random.random()
    x = property(__random)

a = Foo()
print a.x
print a.x

So there's no consistency. With Ruby everything on an object is a 
method, and it's called automatically whether you use () or not. 
Instance variables are hidden.
