Whats wrong with my code?

It returns the correct result in my system. But when i submit the answer it doesnt accept in treehouse.

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(str):
    str = str.lower()
    wordscount = {}
    strlist = str.split(' ')
    for word in strlist: 
        if word not in wordscount.keys():
            wordscount.update({word: 0})

        wordscount[word] += 1
        wordscount.update({word: wordscount[word]})

    return wordscount

The challenge error message contains an important hint. It said: "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", leave the argument to "split" empty. Providing a space causes it to split only on individual spaces.

I tried to leave the argument to "split" empty, but got the same result :(

List = String.split()

Hmm, didn't get the expected output. Be sure you're lowercasing the string and splitting on all whitespace!

This is what I mean by "empty":

str.split()
