How to create environment variables on Azure to access Key Vault

I want to write a Python code to read a secret stored in Azure Key Vault. This code will run on the cloud on an Azure container. It goes like this:

from azure.keyvault.secrets import SecretClient
from azure.identity import DefaultAzureCredential
from azure.core.exceptions import HttpResponseError
import os


VAULT_URL = os.environ["VAULT_URL"]
credential = DefaultAzureCredential()
client = SecretClient(vault_url=VAULT_URL, credential=credential)

print("\n.. Get a Secret by name")
company_secret = client.get_secret('secret_name')
print("Secret with name '{0}' was found with value '{1}'.".format(company_secret.name, company_secret.value))

The thing is, I should specify some Environment variables like Vault URL and I don't know how to do that. I also don't know where I should put my credentials to actually access the Key Vault.

The main question is: how do I establish environment variables?

Thank you

Environment variables are just a dict, so setting them is very similar to getting them.

# Gets env var
VAULT_URL = os.environ["VAULT_URL"] 
# Sets env var
os.environ['URL_VAULT'] = 'Some value'

You may wish to verify they do not exist prior to overwriting:

if 'URL_VAULT' not in os.environ:
    os.environ['URL_VAULT'] = 'Some value'
