Question

I am trying to print frequencies of all words in a text. I wanna print all keys according to their sorted values. Namely, I wanna print the frequencies from most frequent to least frequent. Here is my code:

freqMap = {}
class analysedText(object):

    def __init__(self, text):
        # remove punctuation
        formattedText = text.replace('.', '').replace('!', '').replace('?', '').replace(',', '')

        # make text lowercase
        formattedText = formattedText.lower()

        self.fmtText = formattedText

    def freqAll(self):

        wordList = self.fmtText.split(' ')


        freqMap = {}
        for word in set(wordList):
            freqMap[word] = wordList.count(word)

        return freqMap


mytexte = str(input())
my_text = analysedText(mytexte)
my_text.freqAll()
freqKeys = freqMap.keys()
freqValues = sorted(freqMap.values())
a = 0
for i in freqValues:
    if i == a:
        pass
    else:
        for key in freqKeys:
            if freqMap[key] == freqValues[i]:
                print(key,": ", freqValues[i])
        a = i

Answer 1

Your function freqAll returns a value that you are not catching. It should be:

counts = my_text.freqAll()

Then you use the counts variable in the rest of your code.

Answer 2

freqAll method of your class does return freqMap which you should store but do not do that, therefore you are in fact processing empty dict freqMap , which was created before class declaration. Try replacing

my_text.freqAll()

using

freqMap = my_text.freqAll()
