Code does not Work

This Code seems to work in the workspace but not here.

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):
    dic=dict()
    string=string.lower()
    string=string.split(' ')
    for x in string:
        count=1
        if x in dic.keys():
            count=dic[x]+1
        dic[x]=count
    return dic

I pasted in your code in the challenge and got "Hmm, didn't get the expected output. Be sure you're lowercasing the string and splitting on all whitespace!" (my emphasis). You're currently splitting on one space ' '. If you had a string like:

 "hey    i'm   a     string   with    a   lot   of   spaces"

it would split on one space so you'd actually get ' ' as a word (with a bunch of "count"). Just use the default split() without any arguments. That will split words on all whitespace so you only get a list of words.

Oops! Didn't take that scenario into account.The code works now.

Thanks a ton! :)

When you paste code from workspace or someplace else, sometimes it won't pass the challenge even if it's correct. Try typing it in.
