$1.$ Create a Python program file called Ch$10-2\_$Name.py$.($Replace Name with your initial of first name and first $5$ letters of last name.$$ If your last name is shorter than $5$ letters, just use full last name, it doesn't have to be $5$ letters.$$ i$.$e$.$ if your name is John Doe, your file name should be Ch$10-2\_$JDoe.py$)$

$$

$2.$ Your program will take a file name from user and parse the file.$$ Read and parse the$$ lines that begins with "From" and pull out the email addresses from the line. Count the number of messages from each person using a dictionary.

After all the data has been processed, print the person with the most commits by creating a list of $($count$,$ email$)$ tuples from the dictionary.$$ Then sort the list in reverse order and print out top $5$ users with email usage.$$ Your output should list each email address and frequency.$$

If user enters wrong information $($wrong name of the file or non$-$existing file name$),$ your program needs to display message and ask for correct input.$$ Your program should not generate traceback message with any input.

Do not read the entire file to process.$$ Use only file handle to process it$.$

Sample output

$========================================================$

Enter file name to process:fksaldj;f

File fksaldj;f doesn't exist.

Please enter correct file name

Enter file name to process:mbox$-$short.txt

Here is a list of top $5$ email users:

$====================================$

$8$ zqian@umich.edu

$8$ david.horwitz@uct.ac$.$za

$6$ louis@media.berkeley.edu
