Scientific Computing with Python Projects - Arithmetic Formatter

[jnaroian]

Tell us what’s happening:
When I print out my solution it is perfect, but it doesn’t pass the tests and I can’t understand why.

Your code so far

It’s just occured to me that the formatting of the code I posted here is horrible, is there a way to share my .py or .ipynb file?

[JeremyLT]

I’ve edited your post for readability. When you enter a code block into a forum post, please precede it with a separate line of three backticks and follow it with a separate line of three backticks to make it easier to read.

You can also use the “preformatted text” tool in the editor (</>) to add backticks around text.

See this post to find the backtick on your keyboard.
Note: Backticks (`) are not single quotes (').

[JeremyLT]

It’s easiest if you share the link to your replit so we can see the results of the test suite ourselves.

[jnaroian]

Thank you so much! I couldn’t tell that was the problem from the test cases. Just fixed it and passed all tests!

[jnaroian]

Good to know, thanks for the edit!
