Alan,
Thanks for the reply. This is not homework, it is a hobby. I am 44 years
old. I was using Visual Basic, but recently decided to switch to Linux and
have no intentions of going back to windows. Python seems like a good
computer language. I read somewhere the the best way to learn it was to pick
a project and start programming. Since one of my other hobbies is word games
and Linux is severely lacking in this area I decided to write a game similar
to Text Twist in windows for my first project.
The game I am writing has a graphical front end using GTK and the code so
far is long and in more than one file (to keep the gui code seperate). I
will gladly email you the whole thing to you if you like.
In my research, I looked at examples of permutations, lists, sets, and
most recently dictionaries which I have the feeling is the solution.
Permutation looked good, but I am an amateur programer and couldn't quite
grasp the concepts from the examples I found. Dictionaries hold promise as
it can be used to get a count of the letters in words.
from operator import itemgetter
def countletters(word):
lettercount = {}
for letter in word:
lettercount[letter] =lettercount.get(letter,0) + 1
print sorted(lettercount.iteritems(), key=itemgetter(1))
countletters("batty")
[('a', 1), ('y', 1), ('b', 1), ('t', 2)]
countletters("bat")
[('a', 1), ('b', 1), ('t', 1)]
countletters("bats")
[('a', 1), ('b', 1), ('s', 1), ('t', 1)]
bat is in batty. bats is not.
I have a list of words in wordlist.txt. I can write a loop the do the letter
counts for each word, but I can't figure out how to compare them.
thanx,
kreglet
