Arithmetic operations using lists

[yassine]

Hello everyone,

I'm a beginner in python we are taking a python coding course in my school and we have been assigned a homework to do.
Please how can I make python differentiate between a valid arithmetic operation and an invalid one.
for example :
- Please enter an arithmetic operation: abc
Invalid arithmetic operation!

- Please enter an arithmetic operation: 83*121
Valid arithmetic operation!

1. Don't double post on the forums.
2. What have you tried? Post your coding attempt in Python code tags and errors in error tags if they show up. You can find help here.
If there are no errors you can show the results you get vs. the desired result.
