Solution Key

#'Method 1
def wordcountFun(words):
    wordcount={}
    for word in words.split(' '):
        if word not in wordcount:
            wordcount[word] = 1
        else:
            wordcount[word] += 1
    print (wordcount)
    return wordcount

# Method 2
def wordcountFun1(words):
    wordcount={}
    new=words.lower()
    for word in new.split(' '):
        if word not in wordcount:
            wordcount[word] = 1
        else:
            wordcount[word] += 1
    print (wordcount)
    return wordcount

# Method 3
def wordcountFun2(words):
    wordcount={}
    for word in words.split(','):
        if word not in wordcount:
            wordcount[word] = 1
        else:
            wordcount[word] += 1
    print (wordcount)
    return wordcount
