Python Python Collections (2016, retired 2019) Dictionaries Word Count

Posted by Kirsten Smith

Code is working correctly, still getting an error that it is not complete. I tested in workspaces as well and it works.

I am lowercasing the string, splitting on white space, and setting the correct values for each word. The dictionary outputs correctly in workspaces, but I keep getting the error that the code is not correct.

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(str):
    dict = {}
    str = str.lower()
    words = str.split(' ')

    for word in words:
        dict[word] = 0

    for word in words:
        dict[word] += 1

    return dict

Try running where you put 3 extra spaces between do and Not (sometimes extra spaces are removed from these posts) - or just add extra spaces between any words in your test sentence and see your results:

print(word_count("I do     Not like it Sam I am"))

Hi Kirsten,

You've pretty much got it, except for one small oversight. When you check your code, the error comes back and partly says:

Be sure you're lowercasing the string and splitting on all whitespace!

Your code is splitting on spaces only. While spaces are whitespace, there are also many other characters that are read as whitespace, such as newline returns and tabs. So, you're really not splitting on all whitespace.

Note: This isn't made very clear in the instructions, only in the error message (Tagging Craig Dennis for maybe a fix).

Anyway, remember to split on all whitespace, you just pass no arguments into the split() method. So, just change the split(' ') to split(). The rest is perfect.

Nice work!! :) :dizzy:
