Thanks for taking time to answer. Please notice that OP already tried warnings.simplefilter(action='error', category=ResourceWarning) with no luck. Also, in the answer, Daniel states the following: "The ResourceWarning is indeed being generated during garbage collection, and Python prints a message because it doesn't have a way to raise an exception at that point." If it were true that would have been rather unfortunate as I guess most ResourceWarnings are being generated during garbage collection. In that case to let users get hold on such warnings there would need to be created new mechanism for gathering warnings (not based on exceptions as a mean of transport). -- https://mail.python.org/mailman/listinfo/python-list
