You modified post 8 --- hmm --- maybe you're not finished changing post 8 --- at about the same time of post 15.
I nabbed the 4 files at post 8 (the post with your codes) and ran banking.py. There was an indentation error caused by an if statement without associated code. I inserted a pass statement and ran the program. The output differs from what you reported.

['savings', '0.0125', '1.00', '3']
['checking', '0.195', '10.00', '0.25', '25.00', '100.00']

So we're unsynchronized. If the program works as you say it does you'll probably get a passing grade. It won't be an A.

I don't know that there'd be value to comments about "your code" when you think the program is something different from what I think it is.

Take savings.py. The comment at the fourth line says that your savings account class will inherit BankingAccount . I suggested to make this work you'd have to have savings.py import account . Instead, you discarded the inheritance aspect. With inheritance you need to write common methods only once in the parent class. And then you only have to debug them in one place.

So---I apologize for my first post in which I pointed out that you messed up the capitalization of SUCCESS and FAIL. You asked for comments and this was the first problem I found although by no means the most important. In my opinion the algorithm comes first, and then adjust the content of these constant strings.

I am running into the error you just said about inheritance. With the current code its saying how _balance is not an attribute of savings or checking. I imported account into both of them but it still gives the same errors. Help !!

Following the __doc__ string in savings.py , you could write

from account import BankingAccount

Then, to cause the inheritance you'd write

Code:

class SavingsAccount(BankingAccount):

    def __init__(self, other, args):
         blah
         blech

    def etceteras(self,*args):

My post #2 has a recent, simple example of doctest.
