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

Posted by Todd Teese

I have the correct output, is there anything else to this?

I've tried this in a separate sandbox, and I'm getting the correct output dict, with words for keys and int's for values. Just wondering if there's something I'm doing wrong or weird in this code challenge.

Thanks in advance!

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(inputString):
    wordList = inputString.lower().split(" ")
    wordDict = dict()
    for word in wordList:
      if wordDict.has_key(word):
        wordDict[word] = wordDict[word] + 1
      else:
        wordDict[word] = 1
    return wordDict

You are on the right path. Two errors to correct:

  • dict object wordDict has no attribute has_key. Instead use:
if word in wordDict.keys():
# or the sort version
if word in wordDict:  # .keys() is assumed
  • The split should be on whitespace not a literal " " (space). No argument means split on whitespace.

Post back if you need more help. Good luck!
