How to implement Try Catch error handling in Sikuli Script

Hello,
 When I try to implement the try catch functionality in my script.
Let me explain the scenario first.

I have a file with data
The script goes through each row of the data and dynamically populates data in the software from row 1 and than once it completes the operation it moves to row 2 and continues with the next row of data.

I implemented try catch functionality that should work as follows
try:
   somefunction(passed)
except Exception:
  return(failed)

than the script does a clean up

Basically when I try to implement try, catch functionality and an unexpected issues comes up, I still end up getting internal sikuli errors of image not found, so instead of function returning a failure and continuing on with doing a clean up and moving on to the next row, it fails out in the ide with image not found error.

So my question is, is it possible to do a try an catch error handling with sikuli, and if so how can be implemented?

Thank you.
