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

I'm facing an error while completing the dictionary challenge. Please Help!!

The challenge is to create a function named word_count. It should accept a single argument which will be a string. The function needs to return a dictionary. The keys in the dictionary will be each of the words in the string, lowercased. The values will be how many times that particular word appears in the string.

I get this error when I try to submit ---> Bummer: Hmm, didn't get the expected output. Be sure you're lowercasing the string and splitting on all whitespace!.

My current solution is attached below
# 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):
    lis = str.lower().split(' ')
    dicts = {}
    for s in lis:
        if s in dicts:
            dicts[s] += 1
            dicts[s] = 1
    return dicts

The error presented states to make sure you are splitting on all whitespace. This is accomplished by omitting the separator in the split function. Like this:

 lis = str.lower().split()

Thanks a lot ! That fixed it.
