Loop issues

Question

I’ve tried many, many things this morning, and the best I could do was get my mult() function to run twice. From what I can tell I’m stuck at
if signcheck(ops[o],ready): being always true.
I’m trying to get my script to take an input like (2*5/2)(10-5*3) and get 5, -5. Thanks in advance!
I even left another attempt in the comments. I thought maybe it was having trouble with more than one if statement being true.

Kelvin Paul Thanks for an easy solution to my project, but it doesn’t help me to understand the problem with my code. I like to know and understand my issues for the next time they come up.
