Actual behavior

Run Python File in Terminal does not save the file before running it in the terminal

Expected behavior

Run Python File in Terminal should save the file before running it in the terminal. I've gotten confused a few times when I type something into a file and try to run it, and it produces unexpected results, only to realize I forgot to save.

Steps to reproduce:

1. Create a new .py file
2. Type print("hello world") into the file, but don't save!
3. Right->click in the editor and select Run Python File in Terminal
4. Observe no output (because the file was not saved)
