Let's say I have a file like:

Project0\pizza.py

Project0\make_pizza.py

and pizza:

def make_pizza(size,*toppings):
print("\nMaking a " + str(size)
      + "-inch pizza with the following toppings:")
for topping in toppings:
    print("- " + topping)

and make_pizza:

from pizza import make_pizza 
pizza.make_pizza(16, 'pepperoni')

and as shown in the codes, I want to import pizza into make_pizza, but the IDE shows up an error that there is no module named pizza. How can I solve this problem and import pizza into make_pizza?

    "import pizza into make_pizza" makes no sense. `make_pizza` is a function defined *by* the module `pizza`. If `from pizza import make_pizza` fails, then you haven't configured your IDE properly to find the file `pizza.py`. – chepner Apr 24 '18 at 17:12
  • On reading this again, it's a little confusing, though, because it's not clear why you need a module `make_pizza` that calls `pizza.make_pizza`. – chepner Apr 24 '18 at 17:18

You're importing it correctly, but you're calling it incorrectly.

The correct way to call it is:

make_pizza(16, 'pepperoni')

You imported only the function make_pizza in your make_pizza.py so you can just use make_pizza without redefining pizza (since Python has already loaded this):

from pizza import make_pizza 
make_pizza(16, 'pepperoni')

As mentioned in the comments below you could use this function, but then you would need to import pizza and not just part of it.

    Would just like to add, if you simply did `import pizza`, then your approach of using `pizza.make_pizza(16, "pepperoni")` would work. – SShah Apr 24 '18 at 21:34

because the module directory is not available in the PATH environment variable.

  • I am pretty sure it is. – Xantium Apr 24 '18 at 19:50
  • You can import scripts from the same dictionary – Xantium Apr 24 '18 at 21:53

    I put two .py files in the same folder "Project0"，does it means the two .py files are in the same path? – JoJo Hu Apr 25 '18 at 06:44
  • @JoJoHu Yes there is no path problem in this case. The problem is how you imported the module. If you did put `Project0` in the path environment variable , you could import that project from anywhere. I.e. `import pizza` would work from any dictionary. – Xantium Apr 25 '18 at 08:04
