atm machine problems - jy0013 - Sep-23-2018

I'm having some problems with the type of the account_balance. I'm not 100% sure what to do to change them to the right types. I also need to make sure that the withdrawal is divisible by 10, I know I use the % statement, but I don't know how the line of code would read. Any help is appreciated!

while counter < 3:
    pin = input("Please input your 4-digit PIN: ")

    if pin == 9876:

        break

    print("Incorrect PIN, please try again")

Hi :)
The error occures because this type of string concatenation can be used in print but not generally. change the line 
r = input("Are you sure you want to deposit ", deposit, "? [Y/N]")
to
r = input("Are you sure you want to deposit {}? [Y/N]".format(deposit))
and the error is gone ;) You are calling the input function and giving it these 3 arguments but all it needs is just one string, so you need to put the strings together before using it for input.

The % operator is easy to use. Just as a small reminder:
10 % 10 == 0
20 % 10 == 0
11 % 10 == 1
12 % 10 == 2
...
so just check:
if withdraw % 10 == 0:
     # then everything is good
else:
     # ask the user to input the amount again
What do you want to do in this line?
account_balance = (int, 'Your account balance is: $500')
