Hi, welcome to tutor.

Can you explain exactly how you are running the program because it looks 
below like there are twi distinct things going on.

This looks like you have copied a Python interpreter interactive session 
into a text file and tried to run it as a script. Is that what you did?

If so, that's the problem. You need to separate out what the interpreter 
displayed (its output) from what the interpreter read(its input). The 
interpreters input is all you should have in your program.

Wow, that's quite an advanced first class! I didn't see IPO diagrams 
till my third year at Uni! And then never used them again until I 
started using 6 Sigma as a business analyst at work many years
later... (And even then usually in the context of SIPOC charts...)

Down to here it looks like a perfectly successful interactive session.
Converting that to a script that you can run directly it looks like:

Pizzas = float (input ("Number of Pizzas "))
Length = float (input ("Length of Pizzas "))
Width = float (input ("Width of Pizzas "))
Thickness = float (input ("Thickness of Pepperoni Slices "))
Diameter = float (input ("Diameter of Pepperoni Slices "))
Edge = float (input ("Crust Edge of Pizzas "))
StickLength = float (input ("Length of Pepperoni Sticks "))
UsefulLength = Length - 2 * Edge
SlicesLength = UsefulLength / Diameter
UsefulWidth = Width - 2 * Edge
SlicesWidth = UsefulWidth / Diameter
Slices = SlicesWidth * SlicesLength
TotalSlices = Slices * Pizzas
HypoLength = TotalSlices * Thickness
PepperoniSticks = HypoLength / StickLength
print (StickLength)
print ("You will need", PepperoniSticks, "pepperoni sticks this month.")

And the output when you run it is:

Number of Pizzas 100
Length of Pizzas 11
Width of Pizzas 11
Thickness of Pepperoni Slices .1
Diameter of Pepperoni Slices 1
Crust Edge of Pizzas .5
Length of Pepperoni Sticks 10
10.0
You will need 100.0 pepperoni sticks this month.

So it looks like it all works. We could critique the
style and design but the basic code works.

I suspect your probl;em is that you are trying to save
or cut 'n paste an interpreter session directly into
a python script and that just won't work.
