1. Use three counter variables named counter_com, counter_edu and counter_org to keep track of how many of each you find. Declare these just under the comment with your name/date at the top of the file. 2. Write a program that opens mbox. txt, reads through the file, and finds lines that contain e-mail addresses ending in .com, .edu and .org. Use .find() to identify lines where one of these exist.
3. Define an output file towards the top of your code-named "emails_output. txt" (just do this as the next line after you open the mbox. txt file). Any time you find() a line in mbox. txt that has the .com, .edu, or .org email address in it, increment the proper counter and write the entire line to your emails_output. txt file.
4. Once you have finished reading through the mbox. txt file, print your counter totals.
