The instructions say to "return 'invalid transaction'" but I expect they
really want that error printed to STDERR (typically your screen) rather
than literally returned. Try this:
def withdraw(self, amount):
self.amount=amount
if(amount > self.balance):
print "Amount greater than available balance, no funds withdrawn."
else:
self.balance -= amount
return self.balance
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.
