Python Forum

Howdy,
I do not know what happened, but I do seem to remember that when I started IDLE and opened a python file, the editor and shell windows open as two different windows. Now, the two are combined as "tabs" in one window. I looked at the preferences and did not see any option to combine or uncombined the two.
Did something change or did I perhaps change something?

What version of python?
I'm running the latest python 3.6.5, and idle opens the same as always.
starts as python shell, to open a file, need to either include as a command line argument or open from file menu.

In addition, you should be using one of the many IDE's available. Idle is a poor 'IDE'
