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

what's wrong with my solution ?

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(seq):
    words = seq.lower().split(' ')
    dict = {}
    for word in words:
        dict[word] = 0
    for word in words:
        dict[word]+= 1
    return dict

Hi there! You're doing great, and my guess is that you've tried some test data. I'm also guessing that your test data isn't really comprehensive. Have you tried a string with any tabs or newline characters? :smiley:

The challenge asks that you split on all whitespace. Currently, you are only splitting on spaces. Tabs and newlines are also whitespace.

#This splits on spaces
split(' ')

#This splits on all whitespace
split()

Removing the arguments from the split() function causes it to split on all whitespace.

Hope this helps! :sparkles:
