list - Iterating through a .txt file in an odd way -

what trying write program opens .txt file movie reviews rating number 0-4 followed short review of movie. program prompts user open second text file words matched against reviews , given number value based on review.

for example, these 2 sample reviews how appear in .txt file:

4 comedy-drama of epic proportions rooted in sincere performance title character undergoing midlife crisis . 2 massoud 's story epic , tragedy , record of tenacious , humane fighter prisoner -lrb- , victim -rrb- of history .

so, if looking word "epic", increment count word 2 (which have figured out) since appears twice, , append values 4 , 2 list of ratings word.

how append ints list or dictionary related word? keep in mind need create new list or dicitonary key every word in list of words.

please , thank you. , sorry if poorly worded, programming isn't forte.

all of code:

def menu_validate(prompt, min_val, max_val):     """ produces prompt, gets input, validates input , returns value. """     while true:         try:             menu = int(input(prompt))             if menu >= min_val , menu <= max_val:                 return menu                 break             elif menu.lower == "quit" or menu.lower == "q":                 quit()             print("you must enter number value {} {}.".format(min_val, max_val))         except valueerror:             print("you must enter number value {} {}.".format(min_val, max_val))  def open_file(prompt):     """ opens file """     while true:         try:             file_name = str(input(prompt))             if ".txt" in file_name:                 input_file = open(file_name, 'r')                 return input_file             else:                 input_file = open(file_name+".txt", 'r')                 return input_file         except filenotfounderror:             print("you must enter valid file name. make sure file open in programs root folder.")  def make_list(file):     lst = []     line in file:         lst2 = line.split(' ')         del lst2[-1]         lst.append(lst2)     return lst  def rating_list(lst):     '''iterates through list of lists , appends first value in each list second list'''     rating_list = []     list in lst:         rating_list.append(list[0])     return rating_list  def word_cnt(lst, word : str):     cnt = 0     list in lst:         word in list:             cnt += 1     return cnt  def words_list(file):     lst = []     word in file:         lst.append(word)     return lst  ##def sort(words, occurrences, avg_scores, std_dev): ##    '''sorts , prints output''' ##    menu = menu_validate("you must choose 1 of valid choices of 1, 2, 3, 4 \n        sort options\n    1. sort avg ascending\n    2. sort avg descending\n    3. sort std deviation ascending\n    4. sort std deviation descending", 1, 4) ##    print ("{}{}{}{}\n{}".format("word", "occurence", "avg. score", "std. dev.", "="*51)) ##    if menu == 1: ##        in range (len(word_list)): ##            print ("{}{}{}{}".format(cnt_list.sorted[i],)  def make_odict(lst1, lst2):     '''makes ordered dictionary of keys/values 2 lists of equal length'''      dic = ordereddict()      in range (len(word_list)):         dic[lst2[i]] = lst2[i]      return dic           cnt_list = [] while true:     menu = menu_validate("1. sentiment words in file? \nq. quit \n", 1, 1)     if menu == true:         ratings_file = open("sample.txt")         ratings_list = make_list(ratings_file)           word_file = open_file("enter name of file words score \n")         word_list = words_list(word_file)         word in word_list:             cnt = word_cnt(ratings_list, word)             cnt_list.append(word_cnt(ratings_list, word)) 

sorry, know it's messy , incomplete.

i think mean:

import collections  counts = collections.defaultdict(int)  word = 'epic'  counts[word] += 1 

obviously, can more word have, aren't showing code, ...

edit

okay, looking @ code, i'd suggest make separation between rating , text explicit. take this:

def make_list(file):     lst = []     line in file:         lst2 = line.split(' ')         del lst2[-1]         lst.append(lst2)     return lst 

and convert this:

def parse_ratings(file):     """     given file of lines, each numeric rating @ start,     parse lines score/text tuples, 1 per line. return     list of parsed tuples.     """     ratings = []     line in file:         text = line.strip().split()         if text:             score = text[0]             ratings.append((score,text[1:]))     return ratings 

then can compute both values together:

def match_reviews(word, ratings):     cnt = 0     scores = []      score,text in ratings:         n = text.count(word)         if n:             cnt += n             scores.append(score)      return (cnt, scores)
