Wayne's right. Always give us a full traceback. Where the error
finally shows itself is rarely the same as where it's first started,
and a traceback can tell us that.
That said, you did a pretty good job of removing irrelevant code
(thank you!! it helps us a lot! :), and I was able to find your
particular error. It starts in this snippet:
elif action == "examine":
if len(cmdlist) != 2:
print "An examine command must be followed
by an item name."
continue
else:
character.examine(cmdlist[1]) # <--- right here
the problem is that cmdlist is just a list of strings. Hence
cmdlist[1] is a string as well. And strings don't have the description
attribute, hence python is complaining. What you likely meant is not
to examine not the string, but the item object with a name that equals
that string.
