For this assignment, you'll be coding some string manipulation functions within the string1.py and string2.py files.

There is some light dependency on knowing how Functions work in python in terms of argument passing and return values, but you should be able to figure it out as you go.

Complete all of the string functions in string1.py and string2.py based on your knowledge of Python strings, indexing, slicing, and methods. Make sure all the included tests are passing, before submitting your work.

Run the programs from the command line like this:

$ python string1.py

Here is a sample output. You can see that for the donuts() function, some tests are passing, others are failing.

$ python string1.py

1. Fork this repository into your own personal github account.
2. Then Clone your own repo to your local development machine.
3. Create a separate branch named dev, and checkout the branch.
4. Commit your changes, then git push the branch back to your own github account.
5. From your own Github repo, create a pull request (PR) from your dev branch back to your own master.
6. Copy/Paste the URL link to your PR as your assignment submission.
7. Your grader will post code review comments inline with your code, in your github account. Be sure to respond to any comments and make requested changes. RESUBMIT a new link to your PR after making changes. This is the code review iteration cycle.
