Welcome @wunaizcy
I have a few questions:
- What OS are you using?
- Can you switch to Python Mode (using that mode button at the top-right of the editor)? Did you manage to install Python Mode from the Contribution Manager window?
- Are there any errors in the Console (black area at the bottom of the editor) when you try and run a Python sketch?
- Would you happen to be using some networked account on a Windows machine?
