[issue39212] Show qualified function name when giving arguments error

How did you get the fully qualified exception? I just get "TypeError". (Also the error message is different in 3.8.)

Couldn't you tell from the stacktrace showing the failed line of code?

I don't know about this. While I can certainly see that there are circumstances where it might be useful (e.g. you're running a .pyc file and there's no source line available), I think that in the majority of the cases showing fully-qualified names would be more annoying than useful, and certainly more intimidating to beginners.
