Using environmental variables in bash while executing python script?

Question

I exported variable in local environment, and need to pass that variable into bash script, which in turn will need to run python script using that env.

#!/usr/bin/env bash
export API_TOKEN=836176e9b6ce
sudo python script.py --pretty

Right now I am getting following:

Could not find values for Program api_token.
They must be specified via either ini file, command line argument (--api-token),
or environment variables (API_TOKEN)

Is it possible to achieve?

It's hard to answer this without seeing the script.py code. Is the message you posted coming from bash or python? Are you reading API_TOKEN in the python code? A lot more information is needed to answer this. — Manetho

@bluegreen - yes, it was reading token in the python code - and the message was coming from python script - solution and flag suggested by janos fixed the issue — Halina V

The environment you set in the script is not passed through to the command executed by sudo. To preserve environment variables, use the -E flag:

#!/usr/bin/env bash
export API_TOKEN=836176e9b6ce
sudo -E python script.py --pretty
