Wayne, The reason I used print sorted is that using just print throws a syntax error:
print (lettercount.iteritems(), key=itemgetter(1)) ---> error print lettercount.iteritems(), key=itemgetter(1) ---> error print sorted(lettercount.iteritems(), key=itemgetter(1)) ---> works I don't know why. Seems to me that any of the above should work. mainword = countletters('batty') cmpword = countletters('bat') myfunc(cmpword, mainword) Generates error: Traceback (most recent call last): File "/home/kreglet/bin/test.py", line 23, in <module> myfunc(cmpword, mainword) File "/home/kreglet/bin/test.py", line 13, in myfunc for letter in cmpword: TypeError: 'NoneType' object is not iterable mainword = countletters('batty') print mainword returns None cmpword = countletters('bat') print cmpword returns None Both mainword and cmpword are passed to the function but since the values of each are None the function doesn't work. Is this correct? thanx, kreglet Wayne-68 wrote: > > On Sun, Aug 23, 2009 at 10:01 PM, kreglet <kreg...@gmail.com> wrote: > > I would actually not bother sorting your return from countletters - keep > it > a dictionary. > > Then you can compare like this: > > mainword = countletters('batty') > cmpword = countletters('bat') > > def myfunc(cmpword, mainword): > for letter in cmpword: > if mainword.gets(letter): > if cmpword[letter] >mainword[letter]: > return False > else: > return False > > I think that should work.
