#100324 — Need help on a project To :"Create a class called BankAccount with the following parameters "

Create a class called BankAccount

.Create a constructor that takes in an integer and assigns this to a `balance` property.

.Create a method called `deposit` that takes in cash deposit amount and updates the balance accordingly.

.Create a method called `withdraw` that takes in cash withdrawal amount and updates the balance accordingly. if amount is greater than balance return `"invalid transaction"`

.Create a subclass MinimumBalanceAccount of the BankAccount class

Please i need help on this i am a beginer into python programming.


Also below is a test case given for this project 


import unittest
class AccountBalanceTestCases(unittest.TestCase):
  def setUp(self):
    self.my_account = BankAccount(90)
    
  def test_balance(self):
    self.assertEqual(self.my_account.balance, 90, msg='Account Balance Invalid')
    
  def test_deposit(self):
    self.my_account.deposit(90)
    self.assertEqual(self.my_account.balance, 180, msg='Deposit method inaccurate')
    
  def test_withdraw(self):
    self.my_account.withdraw(40)
    self.assertEqual(self.my_account.balance, 50, msg='Withdraw method inaccurate')
    
  def test_invalid_operation(self):
    self.assertEqual(self.my_account.withdraw(1000), "invalid transaction", msg='Invalid transaction')
  
  def test_sub_class(self):
    self.assertTrue(issubclass(MinimumBalanceAccount, BankAccount), msg='No true subclass of BankAccount')

Start by creating a text file in which you will store your code. Then
create a class called BankAccount, and start adding methods to it.

Which part of this do you need help with?

If you're taking a course on Python programming, you should have met
these concepts. Go and read the course text and see if you can find
the information you need.

No.

You're the one taking the course; you write the code. If you get to
the point of having code that ought to do everything but, for reasons
you don't understand, doesn't, then you can post it here and ask for
help figuring things out. But we're not going to do your homework for
you.

That's easy. Unfortunately, that class does nothing, but at least it exists!
Now all you have to do is create *methods* of the class that do the work.

Here I give it a method called "display_balance" which prints the balance of
the account:

class BankAccount:
    def display_balance(self):
        bal = self.balance
        print(bal)


Notice that the method is indented inside the class.

Unfortunately, that method doesn't work yet. The problem is, the account
doesn't yet have a balance, so obviously trying to print it will fail.
First you need to do the next part of the assignment:


> .Create a constructor that takes in an integer and assigns this to a
> `balance` property.

A "constructor" is a special method that Python automatically used to create
new instances. (I hope you understand what instances are!) Python classes
have two constructor methods:

    __new__

    __init__

Notice that they both start and end with TWO underscores.

Chances are, you won't need to use __new__, you will probably use __init__
instead. (Technically, __init__ is an initializer method, not a
constructor, but most people don't care about the difference.) So you have
to write a method called "__init__" that takes an integer argument (don't
forget the "self" argument as well!) and assigns that to a balance
property.


Here is how you assign a value to a attribute called "name":

    self.name = "Harbey"


And an attribute called "number":

    self.number = 23


And an attribute called "address":


    self.address = "742 Evergreen Terrace Springfield"


See the pattern? How would you assign to an attribute called "balance"? Put
that *inside* the constructor method inside the class.

> updates the balance accordingly.
> 
> .Create a method called `withdraw` that takes in cash withdrawal amount

Again, you need to create two new methods. Remember, you create a method
with "def ..." and indent it inside the class. They must have a "self"
argument, plus whatever extra arguments the instructions above demand.

Here is how you would triple an attribute called "total":


    self.total = 3 * self.total


How would you add or subtract from "balance" instead?


I've given you most of the pieces you need to solve this problem. You just
need to assemble them into working code. Off you go, write some code, and
if you have any problems, show us what code you have written and ask for
help. Just don't ask us to do your assignment for you.

you are absolutely correct Mark 
i'm a beginner in python and  from the original question and test case given above i wrote this 



class BankAccount(object):
    def __init__(self, initial_balance=0):
        self.balance = initial_balance
    def deposit(self, amount):
        self.balance +=amount
    def withdraw(self, amount):
        self.balance -= amount
my_account = BankAccount(90)
my_account.withdraw(1000)
if my_account.balance < 4:
    print('invalid transaction')
class MinimumBalanceAccount(BankAccount):
    def __init__(self, MinimumBalance=4):
        self.minbalance = MinimumBalance





after executing this i got this  TEST SOLUTION ERROR which i don't know what it means

invalid transaction



SO please what is wrong with my code, does it not meet the requirement of the "test case" given above in the question?

It's a start but you've still left things out.  If I run your code as 
given above it outputs "invalid transaction", exactly as expected.  So 
how are you running the code?  Where does the extra output you give 
above come from, presumably the "test case", whatever that might be?

 ^^^^^^^^^^^^^^^^^^
This code probably belongs in the withdraw() method.

While the output is as we'd expect, the program's logic is probably
wrong.  Would not you want to put that logic in the withdraw method to
prevent an invalid transaction?

Hi,

I appreciate that you've made an effort this time to write some code, 
but have you attempted to try to _execute_ any of this? [I can see that 
the answer must be "no"]

If you try to execute it (by writing a test that calls the functions), 
you will get errors. Those errors will help you to fix it. If you get to 
the point where there is an error you really can't work out for yourself 
then you can ask a specific question related to what it is you don't 
understand about the error.

It looks like you're just typing in something and sending it to the list 
first rather than the Python interpreter.

If you want to learn how to program well, then you need to learn how to 
interpret the compiler/parser error messages or exceptions you get and 
work out what is wrong for yourself. You can only do that by running 
your code.

I'll give you a hint - read the words of your assignment very carefully. 
It says "a function" (not "several functions") that "Accepts as the 
first parameter a string". Look at what it then says about the second 
parameter, based on that first parameter.

Work on it from there and when you get really stuck, post the code and 
the Python error you get and why you don't understand it (saying what 
you _think_ it means but why that doesn't help you would also be good).

E.

The most obvious thing that is wrong it that you have 3 functions here with the 
same name. In Python that means: define the first function and bind it to the 
name "manipulate_data". Then define the second and bind it to the same name as 
the first, discarding the first function. The define the third and bind it to 
the same name again, discarding the second function.

Your task is asking for a _single_ function which behaves differently according 
to a parameter which tells it what kind of data is has been given, so you want 
a function which starts like this:

  def manipulate_data(kind, data):

and you are supposed to pass in the string "list", "set" or dictionary for the 
first parameter, and some corresponding list, set or dictionary as the second 
parameter. There should _not_ be default values for either of these.

Instead, your function should examine the "kind" parameter and decide what to 
do. So it would reasonably look like this (untested):

  def manipulate_data(kind, data):
    if kind == 'list':
      ... do stuff with data using it as a list ...
    elif kind == 'set':
      ... do stuff with data using it as a set ...
    if kind == 'dictionary':
      ... do stuff with data using it as a dictionary ...
    else:
      raise ValueError("invalid kind %r, expected 'list', 'set' or 'dictionary'" % (kind,))

Try starting with that and see how you go.

Let's start with your first mistake (because the rest is wrong because of this):

READ YOUR INSTRUCTIONS!
It says "Create a function..."

Your 'solution' creates a list.
A list is NOT a function.
