Question

Python 8.17 LAB: Strings of a Frequency Write a program that reads whitespace delimited strings (words) and an integer (freq). Then, the program outputs the strings from words that have a frequency equal to freq in a case insensitive manner. Your specific task is to write a function wordsOfFreqency(words, freq), which will return a list of strings (in the order in which they appear in the original list) that have a frequency same as the function parameter freq. The parameter words to the function wordsOfFreqency(words, freq) should be a list data structure.

Answer 1

#function definition for wordsOfFrequence

#input-> words "string of strings", freq "integer"

#output -> list of strings have the frequency

def wordsOfFrequency(words,freq):

  words4 = words.upper().split()

  words = words.split()

  words2 = []

  words3 = []

  result = []

  for i in  words:

    if i not in words2 and i.upper() not in words3:

      words2.append(i)

      words3.append(i.upper())    

  for i in range(len(words2)):

    if words.count(words2[i]) == freq or words4.count(words3[i]) == freq :

      result.append(words2[i])

  return result            

words ='apple MaNgo apple Orange orange apple guava mango'

print(wordsOfFrequency(words,2))
