I am locally developing and testing an Azure function in Python. I have these entries added to my local.settings.json file -

  1. {
  2.   "IsEncrypted": false,
  3.   "Values": {
  4.     "CONNECTION_STRING": "Connection String",
  5.     "DEFAULT_AVATAR_URL": "Test-avatar"
  6.   }
  7. }

When I access the bottom value from another section of the code I get KeyError. The imports have been properly added as I do get to access other environment variables.

Below is how I use it -

  1. import os
  3. url = os.environ["DEFAULT_AVATAR_URL"]

Please advise!

I have reproduced in my environment and got expected results as below:

local.settings.json

  1. {
  2.   "IsEncrypted": false,
  3.   "Values": {
  4.     "AzureWebJobsStorage": "",
  5.     "FUNCTIONS_WORKER_RUNTIME": "python",
  6.     "URL": "Test-avatar"
  7.   }
  8. }

One way of doing is calling it in:
__init__.py

  1. import logging
  2. import os
  3. import azure.functions as func
  5. def main(req: func.HttpRequest) -> func.HttpResponse:
  6.     logging.info('Python HTTP trigger function processed a request.')
  7.     s = os.getenv("URL")
  8.     print(s)
  9.     name = req.params.get('name')
  10.     if not name:
  11.         try:
  12.             req_body = req.get_json()
  13.         except ValueError:
  14.             pass
  15.         else:
  16.             name = req_body.get('name')
  18.     if name:
  19.         return func.HttpResponse(f"Hello, {name}. This HTTP triggered function executed successfully.")
  20.     else:
  21.         return func.HttpResponse(
  22.              "This HTTP triggered function executed successfully. Pass a name in the query string or in the request body for a personalized response.",
  23.              status_code=200
  24.         )

Output:

Another way is you can call from a python script inside the app like below:

p1.py:

__init__.py

  1. import logging
  2. import os
  3. import sys
  4. import azure.functions as func
  5. import importlib.util
  7. def main(req: func.HttpRequest) -> func.HttpResponse:
  8.     logging.info('Python HTTP trigger function processed a request.')
  9.     rss('p1')
  10.     name = req.params.get('name')
  11.     if not name:
  12.         try:
  13.             req_body = req.get_json()
  14.         except ValueError:
  15.             pass
  16.         else:
  17.             name = req_body.get('name')
  19.     if name:
  20.         return func.HttpResponse(f"Hello, {name}. This HTTP triggered function executed successfully.")
  21.     else:
  22.         return func.HttpResponse(
  23.              "This HTTP triggered function executed successfully. Pass a name in the query string or in the request body for a personalized response.",
  24.              status_code=200
  25.         )
  27. def rss(snn):
  28.     sp = os.path.join(os.path.dirname(__file__), f'{snn}.py')
  30.     ss = importlib.util.spec_from_file_location(snn, sp)
  31.     mm = importlib.util.module_from_spec(ss)
  32.     sys.modules[ss.name] = mm
  33.     ss.loader.exec_module(mm)

Output:

These are the ways you can call or use them, and I didn't face any errors, and you will not too if you follow the above ways.
