[issue34991] variable type list [] referential integrity data loss

I don't know what you mean by "referential integrity data loss".

I have absolutely no idea how to interpret the wall of output you have provided. If there is a bug here, how do you know it is a language bug rather than a bug in your own code?

We're not here to debug your code for you, especially when the code you provide is incomplete (what's Graph.isGoal?) and not the code you are actually running. There is no print inside the visitedPath function, so how are you getting the output checkvisit "inside def(visitedPath)" as you say?

If there is one difference between the code you run and the code you send us, there could be a hundred differences.

Please provide a *minimal* example of the problem, showing clear input, expected result, and actual result. You might find it helpful to read this page first:

It is written for Java programmers, but the advice applies equally to Python too.
