I'm getting an weird error, but only on sololearn...

Question

In these two codes:
https://code.sololearn.com/WK2JjDoYhYTi/?ref=app
https://code.sololearn.com/W0wM0T8Ik9fW/?ref=app

These two codes work on my Computer and My Phone on other editors, but not sololearn...
can someone help me?? 😅😅

In the codes objects get copied to find different molecules, the error happens when the submit button is pressed.

Answer 2

the first code is iterative the second recursive (second easier to understand the logic... 😅)
and it has nothing to do with the function name, since I changed it in the second code...
