Dear Sagun John David,
Welcome to Microsoft Community.
We understand that you want to know more about Python usage.
According to your description, you have already referred to the corresponding support information and can use Python in Microsoft 365 Business Edition, but regarding the use of Python in Business Basis subscription, we need to explain to you:
Under Business Basis subscription, you cannot use Python functions in Excel.
This is mainly because, in Microsoft 365 Business Basis subscription, you can only use the web version of Office and OneDrive storage space, and you cannot use the Excel application directly.

As for Python in Excel, it can only be used in Excel for Windows at present. This function is not applicable to the Web version of Excel.

Thank you very much for your use and support of the Excel function. You can try to subscribe to other versions to help you use it.
This function is also being gradually updated and recommended to all users. We also recommend that you try to wait for the update after this function. You can also follow our official articles. If there are any updates, we will also update the corresponding instructions. After ensuring that it can be used, you can subscribe to the Microsoft 365 Business Basis program.
Thank you for your patience and understanding.
Best Regards,
