GETTING STARTED:
To begin this homework,
Go to PythonAnywhere.com and log into your own account. Make directory homework under your
account either using the Bash console or the File tab. If you use the Bash console to create the directory,
the command is: mkdir hw
Once the directory is made, crate files as described in the following questions. The instructor and/or TA
will access to your PythonAnywhere account to retrieve and review the files.
WHEN YOU ARE DONE:
When you have completed the homework, save this world document and submit it to Canvas assignment links.
Do not copy and paste the given codes in questions into Pythonanywhere. It will cause errors due to
