Is there a reason why some codes work on the code playground but won't into python on a desktop

Answer 1

Yes, there is. The Code Playground is a virtual sandbox environment and has capabilities limited to those of the virtual machine it runs on.
Memory limits, runtime limits, no remote links, no port connections and so on.

Answer 2

Your own IDE is the best place as you can download and install any module you need. With virtual environments you are limited to only those pre-installed there.

Answer 3

Thank you. Any suggestions on where I can practice and play around with codes.
