Is there a specific format of storing environment variables in .bash_profile? - python-3.x

Question

Following is the python code I am using to send messages to slack. The following code throws an error when I try to get the api_key from environment, but it works perfectly fine when I replace webhook with the actual API key.
import requests
import json
import os
data = {
"text" : "hi there"
}
webhook = os.environ.get("SLACK_API_KEY")
requests.post(webhook, json.dumps(data))
The SLACK_API_KEY is an environment variable which I have stored in .bash_profile folder of my system. The API key has the following format:
https://hooks.slack.com/services/alpha_numeric/alpha_numeric/alpha_numeric
This is how I have stored the API key in my .bash_profile folder:
export SLACK_API_KEY="https://hooks.slack.com/services/alpha_numeric/alpha_numeric/alpha_numeric"
This is the error when I try to export the api_key from environment.

Your env var is it stored correctly, to check your environment variable you could do :echo $SLACK_API_KEY in your shell or you could do env and grep after it.
Pay attention that ~/.bash_profile if for user-specific settings and actions (login shells only) alternatively there is .bashrc which is executed for interactive non-login shells.
I suggest to put your variable in ~/.profile and then don't forget to source ~/.profile or wherever you decide to place you env variable .
If they do not exists you can create them, I recommend this post which explains the differences.
Also you can set the var it directly from the script:
os.environ["SLACK_API_KEY"] = "value"
Did a small test with ~/.bash_profile for your case:
