Change environment variable set in jupyter Notebook with magics

Hope this question is not already answered, I've searched many posts but none of them says how to change an environment variable.

I wanted to load environment variables in .env so followed the steps in this post.

%env "OPENAI_API_KEY"=OPENAI_API_KEY

Then I wanted to see my variable with:

%env OPENAI_API_KEY

Everything worked well but my mistake was to erroneously copy the value for my environment variable. So I want to change it.

I tried dotenv to load this variable again but seems not to work.

Hope you can help me, please.

I tried doing again the same procedure so that it can be changed/updated.

Solution

  • If you made a mistake writing your APIKEY:

    Created a .env with your credentials:

    OPENAI_API_KEY="...erroneous-api-key..."

    You verified:

    %env OPENAI_API_KEY

    And you realized it is wrong.

    You can:

    import os
del os.environ["OPENAI_API_KEY"]

    Then:

    os.environ["OPENAI_API_KEY"]="...right-key..."

    To verify this:

    %env OPENAI_API_KEY

    And the updated api-key should be prompted.
