The instructions say "return", not "print" and the report contains:
self.assertEqual(self.my_account.withdraw(1000), "invalid transaction",
msg='Invalid transaction')
so it _is_ checking the returned result of 'withdraw'.
Not Pythonic (neither is printing to stderr! :-)), but that's something
that can be worked on later.
