How to fix RecursionError: maximum recursion depth exceeded

Question

Here's the question:

07. Define a function named import_zip_codes_json() which imports the zip_codes.json as a list in working directory.

Here's the code:

import json
with open('zip_codes.json') as list:
  zip_codes_json = json.load(list)

(The 'def' line is defined by teacher, and what I've wrote is the below part.)

def import_zip_codes_json() -> list:

    zip_codes_json = import_zip_codes_json()
    return zip_codes_json

type(zip_codes_json)

I got 'list' for my return, and it's right. But after running all the codes, I've got RecursionError.

ERROR: test_07_import_zip_codes_json (__main__.TestMidterm)

RecursionError: maximum recursion depth exceeded

I've searched on Google for solutions, and I've tried to use sys.setrecursionlimit(20000)

import sys
sys.setrecursionlimit(20000)

but I still got RecursionError

How can I fix this?

Why does your function import_countries_json() call itself? Also what is import_zip_codes_json() that you have in your full error traceback? — quamrana

I see you have updated the code in your question to match the full error traceback. So why does your function import_zip_codes_json() call itself? What does that have to do with the snippet above that with the json.load(list) in it? Why does question 07 state: "imports the zip_codes.json"? — quamrana

def import_zip_codes_json() -> list:

    zip_codes_json = import_zip_codes_json()
    return zip_codes_json

The first thing import_zip_codes_json() does is call itself, which then calls itself, which then calls itself.... forever. Or until the stack blows up and you get the error.

Why are you doing this?

@GinoMempin the answer does end with a question, but the text below the code definitely identifies the issue that the OP is asking about.

@MichaelDelgado The question was "How can I fix this?" While it identifies why the recursion error is happening, can't provide a fix without understanding why the OP defined the function like this.... which should be a comment.
