Professor Offenberg teaches an excellent Ethical Hacking class here at HCC$.$ Unfortunately, his

evil twin brother, Darth Offenberg, is the head of the international crime group Offenberg$$s

Unethical Computer Hackers $($OUCH$).$ Hackers from OUCH are trying to penetrate your system.

OUCH always begin with one of three IP address ranges in the first two octets:

$1.168\mathrm{.}193$

$2.224\mathrm{.}174$

$3.233\mathrm{.}012$

You have been forwarded a file called $$ipfile$.$txt$.$ This file contains an unknown number of IP

addresses and the data and time that the IP address accessed your system. Your job is to read

the file, find all the suspect IP addresses that might have been used by OUCH, and produce an

output report to both the screen and to an output file.

$1.$ The program must allow the user to enter in the name of the input file:

a$.$ The program must call a function that receives the input filename as a parameter

b$.$ The program must use a try..except block to test that the file exists; if it does not

exist, the program must display the appropriate error message and allow the

reentry of the filename

c$.$ Once the program determines that the file exists, the function must return the file

handle

$2.$ The program must allow the user to enter in the name of the output file:

a$.$ The program must call the same function as above that receives the output

filename as a parameter

b$.$ The program must use a try..except block to test that the file can be crated; if it

cannot be created, the program must display the appropriate error message and

allow the reentry of the filename

c$.$ Once the program determines that the file can be created, the function must

return the file handle
