I get the expected value when I run my function locally, however the keys are in a different order, which is ok

def word_count(phrase): frequencies = {} lower_phrase = phrase.lower() words = lower_phrase.split(" ") for x in words: if x in frequencies.keys(): frequencies[x] += 1 else: frequencies[x] = 1 return(frequencies)

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(phrase):
    frequencies = {}
    lower_phrase = phrase.lower()
    words = lower_phrase.split(" ")
    for x in words:
        if x in frequencies.keys():
            frequencies[x] += 1
        else:
            frequencies[x] = 1
    return(frequencies)

The challenge error message says "Be sure you're lowercasing the string and splitting on all whitespace!".

To split on "all whitespace" the argument to "split" should be left empty. Specifying a space causes it to split only on literal spaces. You probably didn't notice it in outside testing because you probably just used single spaces as separators in the data.
