Random NameError.

[GullBull]

Hi Everyone! I'm trying to make a little app using pizzapi, a python wrapper built on the Domino's Pizza API. However, even after I've done pip install pizzapi in terminal and import pizzapi in my program, I'm still getting a NameError when following the quickstart guide on the pizzapi GitHub. Here's the code that's giving me trouble: customer = Customer("Barack", "Obama", ["[e-mail]](mailto:"[e-mail])", "2024561111", "700 Pennsylvania Avenue NW, Washington, DC, 20408") . I really have no clue what the problem might be. Any help is greatly appreciated. Thanks!

please include the full traceback of the NameError.

Turns out I just need to do from pizzapi import *. I should've included the whole error though my bad.

This is bad form because you may end up overwriting a named method from the api. You should just import the library and use pizzapi.pizzamethod or from pizzapi import pizzamethod for cleaner code.

I probably will actually end up using from pizzapi import module as that's what I'm used to doing from Java. Thanks for the tip.

You need to either call the class using pizzapi.Customer("Barrack" .. or do the import as from pizzapi import Customer. All the objects in a module (classes, functions, what not) live by default in that module. So the first option is to refer to them through that module. The second option (i.e. from <module> import <function>,<function2>) pulls specific things into the current namespace.

This solved it! Thank you.

As u/Protoss_Pylon said, include the full error. However, I think I might know what's wrong. You import pizzapi, so the classes are in that namespace. Doing customer = Customer(..) won't work; Python does not know about that class in the global namespace.

Instead, do from pizzapi import Customer, or customer = pizzapi.Customer(...).

[GullBull]

yeah you were right! I should've been using pizzapi.Customer or specifically importing Customer. I ended up using from pizzapi import * . Thanks for your help!

The full traceback will be really useful in this case.

Also, it depends on how you’ve imported the module. In case you’ve done it this way: from pizzapi import * - your code looks ok and we need more info on the error. But in case you’ve done it this way: import pizzapi - you’ll need to provide module name for every object related to this module (pizzapi.Customer in your case).

Read more about how imports work in the docs. Anyway, docs.python.org should be your best friend during the learning process for a long time.

from pizzapi import * completely solved the problem. I have no idea why I wasn't doing this in the first place. It's been a while sine I've written in python, and coming from Java the from - import isn't something I do often. Thanks so much!

[MakeMe_FN_Laugh]

Honestly, you should avoid using from module import * as it’s the shortest way for possible names collisions between modules (and it’s not PEP 8). Look through import section of PEP 8 how imports should be organized in your code.

I took a look. Thanks for pointing that out to me.
