this PR includes replacement of () with [] as When accessing the environment variable, it should use os.environ['password'] instead of os.environ('password').

This looks good. There two more copies of the typo in automate-secret-santa-emails-with-smtp.mdx as well. Can you update these in this same branch so we can knock out everything at once? 🙏

[Anjalisharma8072]

I am sorry but i only find one copy of it and additionally also added the missing comma

Oh sorry, I thought this was the solution file! I meant two in the MDX, and one more in the actual solution file. 😭
Do you mind adjusting the solution file as well? 🙏

[Anjalisharma8072]
