The code that you posted isn't complete enough to run (since you didn't provide a definition of wordlist), and just generates a NameError exception. Beyond that, I don't understand what the code is supposed to produce for output. As written, you generate a list in your loop and assign it to the name ngrams, but never do anything with that list. Since you're inside a for loop, your ngrams name is overwritten the next time you run through the loop. You also generate a string with the statement "Finished the %d-gram list." % n, but you don't do anything with it. You probably want to either print it, or assign it to a variable to print later. Something like this: wordlist = ['apple', 'orange', 'pear', 'banana', 'coconut'] N = [2,3,4,5] ngramlist = [wordlist] for n in N: ngrams = [' '.join(wordlist[i:i+n]) for i in range(len(wordlist)-n+1)] print "Finished the %d-gram list." % n print ngrams produces the following output when run as a script: Finished the 2-gram list. ['apple orange', 'orange pear', 'pear banana', 'banana coconut'] Finished the 3-gram list. ['apple orange pear', 'orange pear banana', 'pear banana coconut'] Finished the 4-gram list. ['apple orange pear banana', 'orange pear banana coconut'] Finished the 5-gram list. ['apple orange pear banana coconut'] Does that help? -- Jerry _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
