Rydish, a language created for the sole purpose of an RPG. The only problem is
when I enter a word that has not yet been translated, I get this error:
Traceback (most recent call last):
File "translator.py", line 25, in<module>
Etranslate()
File "translator.py", line 14, in Etranslate

KeyError: 'world'
Is there a way to print a user-freindly message instead of displaying a
traceback?

Even easier than catching an exception is to test for the condition you
expect might not pass. Assuming your Edictionary is a dict, all you
need to do is to make the reference conditional on the presence of that
particular key.
if Eword in Edictionary:
print(Edictionary[Eword])
else:
print("oops....
But note the comparison between LBYL and EAFP - I'll leave those
interested to google for it :)
