If you had initialized your "game" dict with

player1 = dict(score=0)
player2 = dict(score=0),

game = dict(
     player1 = player1,
     player2 = player2
     player = player1
     # ...
     )


you wouldn't need the test on
   game['player'] == game["player1"]

, and could just use:

   game["player"]["score"] += 1

.strip() returns a copy of the string without leading and ending 
whitespaces (inlcuding newlines, tabs etc). .lower() returns a copy of 
the string in all lowercases. Since .strip() returns a string object, 
you can chain method calls.

" yaDDA\n".strip().lower()

is just a shortcut for

thestring = " yaDDA\n"
tmp1 = thestring.strip() # => "yaDDA"
tmp2 = tmp1.lower() # => "yadda"

Quite close... You still failed to understand how dicts could be used to 
   replace 'if/else' statements (dict-base dispatch is very idiomatic in 
Python, and is also a good introduction to OO).

Yeps. That's probably why most of us here fell in love with Python: it 
makes simple thing simple, and tend to JustWork(tm).

rewrite it once again using objects instead of dicts ?

Anyway, thanks for sharing your enthusiasm with us.
