Making Faces

Before there were emoji, there were emoticons, whereby text like :) was a happy face and text like :( was a sad face. Nowadays, programs tend to convert emoticons to emoji automatically!

In a file called faces.py, implement a function called convert that accepts a str as input and returns that same input with any :) converted to 🙂 (otherwise known as a slightly smiling face) and any :( converted to 🙁 (otherwise known as a slightly frowning face). All other text should be returned unchanged.

Then, in that same file, implement a function called main that prompts the user for input, calls convert on that input, and prints the result. You’re welcome, but not required, to prompt the user explicitly, as by passing a str of your own as an argument to input. Be sure to call main at the bottom of your file.

Hints

  • Recall that input returns a str, <https://per docs.python.org/3/library/functions.html#input>.
  • Recall that a str comes with quite a few methods, per https://docs.python.org/3/library/stdtypes.html#string-methods.
  • An emoji is actually just a character, so you can quote it like any str, a la "😐". And you can copy and paste the emoji from this page into your own code as needed.

Before You Begin

From the root of your repository execute cd 0-FunctionsVariables So your current working directory is ...

	/0-FunctionsVariables $:

Next execute

	`mkdir faces`

to make a folder called faces in your codespace.

Then execute

	`cd faces`

to change directories into that folder. You should now see your terminal prompt as /0-FunctionsVariables/faces $. You can now execute

	`code faces.py`

to make a file called faces.py where you’ll write your program.

How to Test

Here’s how to test your code manually. At the faces/ $ prompt in your terminal: :

  1. Run your program with python faces.py. Type Hello :) and press Enter. Your program should output:

     Hello 🙂

  2. Run your program with python faces.py. Type Goodbye :( and press Enter. Your program should output:

     Goodbye 🙁

  3. Run your program with python faces.py. Type Hello :) Goodbye :( and press Enter. Your program should output:

     Hello 🙂 Goodbye 🙁

Commit your program to GITHUB

At the /0-FunctionsVariables/faces $ prompt in your terminal:

	git add -A

Add all changed files in the repository to be committed

	`git commit -m “Upload completed faces.py“`

Commit all changes in the REPO with the comment “Upload completed faces.py“ note: If the file is not complete, adjust the comment to describes what is being commited

	`git push`

Push all changes to the REPO
