i don't know what i'm doing on this one

need help

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(x):
    for word in x.split():

Good start.

And you could lowercase the string as you split it. You might start by declaring the (empty) dictionary that you will build. Then in your loop, you could check if each word is already in the dictionary and increment the count if so, otherwise add it in with a starting count of 1.

Then just return the dictionary when the loop is done.

Do you mean increment a value already present? Then something like :point_right: mydict[key] += 1
Or if you mean add a new key and value :point_right: mydict[key] = 1
