Python Python Collections (2016, retired 2019) Dictionaries Word Count

work count challenge

Hello this code works in my terminal but not in the challenge, do you know why ? Thanks !

wordcount.py
# E.g. word_count("I do not like it Sam I Am") gets back a dictionary like:
# {'i': 2, 'do': 1, 'it': 1, 'sam': 1, 'like': 1, 'not': 1, 'am': 1}
# Lowercase the string to make it easier.

def word_count(string):
    string_list = string.split()
    dico_string = {}
    for words in string_list:
        dico_string[words.lower()] = string.count(words) 
    return dico_string

Hey there,

You need to lowercase your string at the beginning you can do this by chaining methods together:

    string_list = string.lower().split()

Then, your for loop needs to reference string_list, not string. The way you have it written, your for loop is counting words that are not capitalized and not counting words that are capitalized. I tested those corrections on your code block and passed the challenge. Hope this helps!

For clarity:

def word_count(string):
    string_list = string.lower().split() # lowercase everything in the string, then split it by all whitespace.
    dico_string = {}
    for words in string_list:
        dico_string[words] = string_list.count(words)  # Removed .lower() and referenced string_list instead of string
    return dico_string

Thanks ! So if i got it right, in "string.count(words)", words i lowered because i did words.lower() just before ?
