anyone please explain me how every line of this working
# 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(a_string):
# Convert 'a_string' into lower case and break it up into a list
words = a_string.lower().split()
# Declare an empty dictionary, ready to be populated
dictionary = {}
# For each item in the list, use the 'count()' method to tally how
# often it appears. Then, populate the dictionary with a key (the word)
# and its corresponding value (the count).
for word in words:
dictionary[word] = words.count(word)
return dictionary
print(word_count("I do not like it Sam I Am"))

4,885 PointsEverything seems to be fine, the only thing I'd say is you probably shouldn't have the print section in the code there as most times they only want you to return the value not print out the function itself.
I'd also try avoiding using names like dictionary or dict to name your dictionary, maybe something like word_dict ?
Reason for that is to give it a meaningful name that is related to the function.
