RE: Unit 18 Procedural Programming Python - Terafy - Dec-17-2017

You defined the function:

def newbalances(initialbalance, productname, advertisingcost):
    ...

But you didn't called the function.

Example of calling a function:

someVariableName = newbalances(inputParameter0,inputParameter1,inputParameter3)

unfortunately we don't know your input parameters.

I have added the = sign to call the function but now have another issue. I will post it in the forum. thank you

RE: Unit 18 Procedural Programming Python - j.crater - Dec-17-2017

@kanwal121
Please post your code in Python code tags and error message in error tags.
See help here.
Edit:
Thanks!

RE: Unit 18 Procedural Programming Python - Terafy - Dec-17-2017

You need a naming convention... you used newBalance as a function name and a variable... that's a no-no

while days>0:
    days = days + 1

that loop will never end. Because days will always be >0

updatedBalances = (newBalance + salesFigure - dailyexpenses) #this is to display the newbalnce on the users screen

there's no variable called newBalance or dailyexpenses from line 39 to 58. That why you have that error.

    sold = salesFigure // priceOfProduct - shopPrice
    if (sold > shopPrice):
        lackOfStock = sold - stock
        costProfit = lackOfStock*priceOfProduct #this is a block of code for If statement showing working out for handling products sold and in stock 
        sales = sales - costProfit

bunch of missing variables.

Anyways what j.crater was telling you before. The variable you define in your function are local variables. You can't grab the local variable and use in the main code or other function. You would need to create the variables again.

RE: Unit 18 Procedural Programming Python - kanwal121 - Dec-17-2017

that loop will never end. Because days will always be >0
you have replied to the loop message. What calculations will end the loop please?

RE: Unit 18 Procedural Programming Python - Terafy - Dec-17-2017

I just read your code (I didn't run your code) and pointed what is potentially wrong with it. It you can give the missing information your code would work.
