Is this correct way to import python scripts residing in arbitrary folders?

Question

This snippet is from an earlier answer here on SO. It is about a year old (and the answer was not accepted). I am new to Python and I am finding the system path a real pain.

Answer 1

I would be worried that your script name might correspond with a module that shows up earlier in the path. To dispel this fear, I would fully replace the path with a new list containing just the directory containing the module, then put it back once the import has completed. Also, you should wrap this in some sort of lock so that multiple threads trying to do the same thing don't interfere with each other.
