3.4 is long out of maintenance, please create a new issue if you are seeing this problem on a current version (>= 3.9).

You are more likely to receive a response if you include a precise and complete description of the problem. For example, instead of saying "The example on your website", put a link to this example.   I'm not sure what the "multiply.py" script you mention is.   The less detective work a core dev needs to do just to understand the issue, the more likely they are to want to look into it.
