Reset / Clear Memory in Python Window

MatthewLeonard — Tue, 21 Apr 2026 12:59:39 GMT

In the Python Window (not notebook), I want to be able to clear the memory of whatever has been run so far and start with a clean slate (similar to restarting the kernel in notebooks). It seems the only way to do this is to close and reopen Pro, which is very inconvenient.

I often use the Python Window for experimenting with code, and I often want to start over without variables/functions/etc. already being defined and stored in memory. I can clear the transcript, but this does not clear memory.

I'm honestly surprised this is not already possible.

@MatthewLeonard It seems this issue likely faces the same challenge with the python dlls @HannesZiegler mentions in this idea: Reset Kernel without Restarting Pro - Esri Community It does appear there is progress toward implementation.

Would `globals().clear()` do what you want in the meantime? I don't fully understand what it does, but it did appear to clear any variables or functions I had defined.
