 #### Using Python
 
-Here is a similar script for generating a JWT in Python. Note you will have to use `pip install jwt` in order to use this script. This script will prompt you for the location of your PEM file, or you can pass it as an inline argument when you execute the script. Replace `YOUR_APP_ID` with the ID of your app. Make sure to enclose the value in single quotes.

 Use your {% data variables.product.prodname_github_app %}'s identifier (`YOUR_APP_ID`) as the value for the JWT [iss](https://tools.ietf.org/html/rfc7519#section-4.1.1) (issuer) claim. You can obtain the {% data variables.product.prodname_github_app %} identifier via the initial webhook ping after [creating the app](/apps/building-github-apps/creating-a-github-app/), or at any time from the app settings page in the GitHub.com UI.
