Help with Word Count. My function returns what I think is correct, but upon submission it fails.

def word_count(phrase):
    space_index = []
    key_list = []
    phrase = phrase.lower()
    count = 1

    for letter in phrase:
        upto = phrase[0:count]
        if letter == " ":
            space_index.append(len(upto)-1)
        count += 1

    count = 0
    key_list = [phrase[0:space_index[0]]]
    for num in space_index:
        try:
            nums = space_index[count:count+2]
            key_list.append(phrase[nums[0]+1:nums[1]])
            count += 1
        except IndexError:
            continue

    key_list.append(phrase[space_index[len(space_index)-1]+1:len(phrase)])

    counter = []
    count= 0
    for num in key_list:
        counter.append(count)

    count = 0
    for item in key_list:
        for thing in key_list:
            if thing == item:
                counter[count] += 1
        count += 1

    my_dict = dict(zip(key_list, counter))
    return my_dict

As said Kenneth in the future courses, Maybe you need to look at editing? :) I mean, try to understand this code or find another solution here on forum, and you won't have to make a mountain out of a molehill: 

def word_count(string):
    string = string.lower().split()
    dic = {}
    for word in string:
        if word in dic:
            dic[word] += 1
        else:
            dic[word] = 1
    return dic

You have done a great job, but try to simplify your code. Below you can find my code which works, please study it and see if you can gain anything from it. This code works but I also need find a way to simplify it even further.

myword ="I do not like it Sam I Am"

def word_count(sentence):
  my_dict = {}
  sentence = sentence.lower().split()
  for sen in sentence:
    if sen in my_dict:
      count = my_dict[sen] + 1
      my_dict[sen] = count
    else:
      my_dict[sen] = 1
  return my_dict
