word_count - trouble with my code

I just keep getting bummer try again. It works on my computer so I'm not sure why it's not working here.

wordcount.py 
def word_count(string):
    list_of_words=string.lower().split(" ")
    my_dict={}
    count=0
    for word in list_of_words:
        if word in my_dict:
            my_dict.update({word:count+=1})
        else:
            my_dict.update({word:count = 1})
    print(my_dict)

word_count("I do not like it Sam I Am")

As Pete mentioned, the split should be on whitespace (the default with no argument) instead of a literal space

Other errors to fix:

  • the print should be a return
  • when using update, use a value instead of an assignment statement
  • to update an existing value add one to the present value my_dict[word]+1

Since you're accessing the current value in my_dict, a short cut would be to update it directly instead of using update: my_dict[word]+=1

Post back if you need more help. Good luck!!!

Try removing the quotes from .split():

list_of_words=string.lower().split()

That way, I believe all types of whitespace will be removed.

Also, I'm guessing the last line of code was included just for testing purposes. It doesn't need to be in your final answer.
