def withdraw(self, amount):
if self.balance < amount:
return 'Invalid transaction'
had done this, this was the condition stated in the question

else: what happens?

cheks100:


else: what happens?

tanks for d time

else:
self.balance -= amount

return "Valid Transaction"

miketayo:

tanks for d time

else:
self.balance -= amount

return "Valid Transaction"

If that worked, then congrats.! I would have suggested you return the balance.

It didn't work

miketayo:

Then return the balance.

cheks100:

def withdraw(self, amount):
if self.balance < amount:
return 'Invalid transaction'
else:
self.balance -= amount
return self.balance

still didnt work

miketayo:

if self.balance < amount:
return 'Invalid transaction'
else:
self.balance -= amount
return self.balance

still didnt work

Yes, it won't work, I just checked your code again and you have "Invalid transaction" instead of "invalid transaction". i is in lowercase not uppercase.
If you do this i think your withdraw function would be ok, that is no more "Failure in line 23, in test_invalid_operation self.assertEqual(self.my_account.withdraw(1000), "invalid transaction", msg='Invalid transaction') AssertionError: Invalid transaction".

Ur d best tanks alot worked.. Python is really different m use to Java and c++ things in quotes r like comments. Tanks alot

its obvious dese guys do Xmas. Code wet no gree submit yesterday submit at once today

Bro, please explain how you wrote your code, 'cause upon investigation, I detected an error in the test code andela wrote on their page.

Someone please add me to the whatsapp group: 08074621118, thanks.

how did u do the OOP lab? am stuck with one error nd my code seem correct

Hi, have you been able to resolve the ds lab error.
If yes, please tell me how you did it.
Thanks.

cheks100:


All you have to know is that your program should be capable of manipulating the three listed D.S ('list', 'dictionary', 'set') and produce the appropriate results. I initially thought I had to pick one but that gave me error.
Think of how to achieve each one separately and then bring all together.

Hi, could you please elaborate how you merged all three under one function?
I'm kind of stuck here.
Thanks.

hi, I am having am error in my OOP Lap test, the code seem correct but it keeps showing this error "Failure in line 23, in test_invalid_operation self.assertEqual(self.my_account.withdraw(1000), "invalid transaction", msg='Invalid transaction') AssertionError: Invalid transaction"

wat does it mean?

That seems to be the unit test failing, are you writing unit test? if yes, you might want to take a look at it, but if you are not writing unit test it means that the application test is breaking, maybe a bug or the way your script is structured.

Yeah I was getting 1 error, I spelt my invalid transaction wrongly. That was all

Hi! Thanks for the response.
But I wasn't referring to the OOP lab. Was actually talking about the ds lab.

I think there's something wrong with the test code written by andela. I compared that of ds lab with the one written for the OOP lab and I discovered that there was something missing there.

In the OOP lab's code, they used "unittest.Testcase" but in that of DS they only used "Testcase".
Based on my little knowledge, the used a universal import but forgot to include the "unittest".
I might be wrong though, so I stand corrected.

Wat errors r u getting?

Maybe you did't understand the question. your function should be able to return different Ds base on the input. And that is possible using conditions in python. I hope you understand what I am trying to say here. Just use three different conditions.

But I tried all three options provided in the test but still got the same error for either trials.

Initially, I thought my code was incorrect as well, but I tried them out on codecademy and the codes worked.

I also copied their tests code and tried them out on codecademy only to get the same error as the one I got on the test page (invalid syntax).

However, I added the "unittest" omitted in their code and it worked.

I'm really confused right now 'cause I've tried my code on several online python consoles and they've been correct on all of them.

I also tried submitting without testing, but got the same error.

Someone should please help out.

Wat errors r u getting?

Here's a snapshot of the error below.

forjamb:


Here's a snapshot of the error below.

these r syntax errors, like that list shouldn't be in quotes "list" am sure there r more .. syntax errors r definitely the programmers fault.. chk ur code again

forjamb:


Here's a snapshot of the error below.

From the error message.. The manipulate_data function is declared with a string arg "list" instead of a valid variable name list.

I was only following the instructions given.
I also tried without the quotes but still nothing.

I'm at my wits end here. I've tried every trick in the book.
Someone please help out.

You can merge all three by using the if and elif. If the data structure is list do this, if it is a set do that etc, according to the instructions given.

Someone please help out.

1. Calm down.
2. Post the new error code when you are done removing the quotation marks from "list"
3. Remember that you can't use the word "list" (without the quotes) as a placeholder in ur code. Use something else.

In the algo lab, 1 (one) was referred to as a prime number. which is not true. one is a composite number since prime numbers should have only two factors. I had a lot of issue with that in the course of coding until i realise they meant one to be a prime number.

How did you return a set to print in {} instead of set([])?

stereo:


How did you return a set to print in {} instead of set([])?

Why do you want to do that?

forjamb:
I'm at my wits end here. I've tried every trick in the book.

Bro it's basically like this:

def manipulate_data(data_structure, data):
If type(data) == type(''):
#manipulate data here
elif type(data) == type({()}):
#manipulate data here
elif type(data) == type({}):
#manipulate data here

I had problems with this same section too but this was how I finaly solved it. It should work for you too. Goodluck..

mayoadegbola:


Why do you want to do that?

Because my output is: set(['a', 'c', 'b', 'e', 'd', 'AFRICA', 'TIA', 'ANDELA']) after using add() to attach the last three strings

and expected output is: {'a', 'c', 'b', 'e', 'd', 'ANDELA', 'TIA', 'AFRICA'}

So here lies the problem. Any help?
