As you're writing a translator it may be interesting to swap in 
something that can still be used in the translation.  No one's mentioned 
get as an option:

 >>> Edict = dict(zip('abcde','ABCDE'))
 >>> for ii in 'agbdteabcdfe':
...     print Edict.get(ii,'-grumble-')
...
A
-grumble-
B
D
-grumble-
E
A
B
C
D
-grumble-
E
 >>>


Or spice it up!

 >>> import random
 >>> undefined = ['-grumble-','-mumble-','-garbled-','-cough-']

 >>> for ii in 'agbdteabcdfe':
...     print Edict.get(ii,random.choice(undefined))
...
A
-mumble-
B
D
-grumble-
E
A
B
C
D
-cough-
E
 >>>
