How do I do this using python

Assignment 1 1 Write a program that prompts the user to enter a text file name (either mbox.txt or mbox-short.txt), then creates a dictionary to count how many messages have come from each email address. You should look for lines starting with 'From ' in the text file. At the end of the program print out the contents of your dictionary (order does not matter). Hint: review Exercise 1 Example: Enter file name: mbox-short.txt {'gopal.ramasammycook@gmail.com': 1, 'louis@media.berkeley.edu': 3, 'cwen@iupui.edu': 5, 'antranig@caret.cam.ac.uk': 1, 'rjlowe@iupui.edu': 2, 'gsilver@umich.edu': 3, 'david.horwitz@uct.ac.za': 4, 'wagnermr@iupui.edu': 1, 'zqian@umich.edu': 4, 'stephen.marquard@uct.ac.za': 2, 'ray@media.berkeley.edu': 1}
