# Scientific Computing with Python Projects - Arithmetic Formatter

hi, i can make this program works idk whats wrong, i get 4 of 6 passed

i search for a ton of help but i cant make it work pls help.
thats my code:

Please post the full error message so we can see what’s wrong with your code. Thanks

i cant put all the errors

You added enough for me to be able to see what’s happening. Thanks

This says that you are adding 4 extra spaces at the end of every row

I’ve edited your code 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 (').
