Question

Python lab: Problem Statement: In this lab, you will be building a software application that will print the most popular ice-cream flavor among kids. Lab Scenario: 1. You are given an input file flavors.txt. One sample example of the file is given below. 2. You will design a user-defined function most_favorite_flavor() which will return the name of the popular flavor. 3. The main function is responsible reading from the file and calling the most_favorite_flavor() function. 4. For this lab, you must have at least two user-defined functions: most_favorite_flavor() and main(). 5. You MUST use a dictionary data structure to determine the count of each flavor a. You then calculate the most popular flavor from the dictionary items. Sample 1/0: Sample Input file: Each line has a name of a kid and the flavor of ice cream she had (separated by space) Jake vanilla Jane chocolate Jill vanilla Mary strawberry Janet chocolate Mika chocolate Sample Output: The most popular flavor is: chocolate

Answer 1
