Is Python a functional programming language?

I'm not talking about nested bindings.  I'm talking about two different
bindings of the same symbol in the same scope:

    $ cat meow.hs
    x = 3
    x = 4
    $ ghc meow.hs

    meow.hs:2:0:
        Multiple declarations of `Main.x'
        Declared at: meow.hs:1:0
                     meow.hs:2:0
