word_count code challenge

I run this in workspaces and it gives me exactly what I'm looking for. Why is this not passing?

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(st):
    my_dict = {}
    words = st.lower().split(" ")
    for word in words:
        my_dict.update({word: words.count(word)})
    return my_dict

When I tried your code I got this hint message: "Bummer! Hmm, didn't get the expected output. Be sure you're lowercasing the string and splitting on all whitespace!"

To split on all whitespace, the argument to split should be empty. Supplying an argument of a space causes it to split only on spaces.

Ah awesome, thanks. I thought you needed to specify what to split on, ie " " being a single space, but I guess that doesn't cover two spaces etc etc. Nice!

def word_count(string): word_count = {} string = string.lower().split()

 for word in string:
     if word in word_count:
         word_count[word] += 1
     else:
         word_count[word] = 1

retrun word_count
