The purpose of this question is to write a complete Python program that computes the frequencies of palindromes in some English language text. The text is in a file named relativity.bxt, which you must download from Moodle. Insert the following function near the beginning of your program. def getWords(filename): filename -> list of words from the file Given the name of a file return a list of words from the file. = filename - the name of the file containing the words #infile - the file descriptor data-the content of the file as one string infile = open(filename, Y) data = infile.reado infile.close retum data split Later in the course we will learn what each statement does. This function reads the text from the file and splits the file up into a list of words and then returns the list of words. Write a function that begins with the following header: def is Palindrome(word): This function is given a string of characters known as word. The characters might not form an actual word, but that doesn't matter. The word is a palindrome if there are at least three characters in the word and the characters read the same from right to left and from left to right. For example, the word level is a palindrome. Return True if the word is a palindrome, otherwise return False. Note: You are not allowed to use the reverse function or slices in this function. Write a function that begins with the following header: def findPalindromes(text) This function is given a list of strings named text. Most of the strings are words but some of them are not, but that doesn't matter. Create two lists named palindromes and frequencies. The list palindromes holds the unique palindromes from the list named text. The list frequencies holds the frequencies of the unique palindromes. For each word in text call isPalindrome to determine if the word is a palindrome. If the word is a palindrome and is not in the list of palindromes add the word to the list of palindromes and add 1 to the list of frequencies. If the word is a palindrome and is in the list of palindromes add 1 to the corresponding frequency in the list of frequencies. Return the list of unique palindromes followed by the list of the frequencies of the palindromes. Hint: The index function can be used to find the position of the palindrome in the list of palindromes. Write a function that begins with the following header: def displayPalindromes(palindromes, frequencies): This function is given the list of palindromes and the list of frequencies. Create a new list that holds the palindromes sorted in ascending order. Use the sorted function to do this. Display the heading as shown in the sample run of the program. Display the palindromes in ascending order along with the associated frequencies one pair of values per line as shown in the sample run of the program. The palindrome is left justified in 20 character positions. The frequency is in 9 character positions. This function does not return anything, Write a function that begins with the following header: def main This function does the following: prints a line of dashes using string replication calls input to get the name of the file containing the text loops as long as the name of the file is an empty string in the loop: o displays the error message as shown in the sample run of the program o calls input to get the name of the file containing the text calls getWords to get the list of words that make up the text calls findPalindromes to get the lists of palindromes and frequencies calls displayPalindromes to display the lists of palindromes and frequencies calls display Termination Message to display the termination message The main program, not to be confused with the function named main, contains all the import statements, the functions and a call to the function named main.
