Python Concordance program - alphabetical order -


i'm trying write program displays concordance file. should output unique words , frequencies in alphabetical order. have, it's not working. tips?

fyi - know nothing computer programming!! i'm taking class satisfy high school math endorsement requirement.

f = open(raw_input("enter filename: "), "r") mydict = {} linenum = 0  line in f:   line = line.strip()   line = line.lower()   line = line.split()   linenum += 1  word in line:     word = word.strip()     word = word.lower()      if not word in mydict:         mydict[word] = []      mydict[word].append(linenum)   print "%-15s %-15s" %("word", "line number") key in sorted(mydict):     print '%-15s: %-15d' % (key, mydict(key))

you need use mydict[key] getting dictionary. , since that's list, need use sum(mydict[key]) frequency (count) 

f = "hello hello hello doing" mydict = {} linenum = 0  word in f.split():     if not word in mydict:         mydict[word] = []      mydict[word].append(linenum)   print "%-15s %-15s" %("word", "frequency") key in sorted(mydict):     print '%-15s: %-15d' % (key, len(mydict[key]))

results in:

word            frequency            : 1 doing          : 1 hello          : 3           : 1            : 1
