Python data structures: Assignment 9.4

Coursera: Python data structures Assignment 9.4 Week 5 9.4  Write a program to read through the  mbox-short.txt  and figure out who has sent the greatest number of mail messages. The program looks for 'From ' lines and takes the second word of those lines as the person who sent the mail. The program creates a Python dictionary that maps the sender's mail address to a count of the number of times they appear in the file. After the dictionary is produced, the program reads through the dictionary using a maximum loop to find the most prolific committer. Solution: name = input("Enter file:") if len(name) < 1 : name = "mbox-short.txt" handle = open(name) count = dict() for line in handle:     word = line.split()     if line.startswith('From '):         count[word[1]] = count.get(word[1], 0) + 1 largest = 0 email = '' for key in count:     if  count[key] > largest:         largest = count[key]
