Change Style of IDLE Python

I want to change the style i.e. theme, button style, font and other items. I can change its style by my own if I can locate the IDLE.py file. So I want to know either of 2 things --> Where is IDLE located? --> or How to change everything of it? Please Help me in getting any of these!

Solution

  • The IDLE application consists of multiple files in <python-dir>/Lib/idlelib. The idle.py file in that directory is just a startup file.

    The editor/shell font can be configured in the Fonts tab of the settings dialog open by Options => Configure IDLE (or IDLE => Setting on macOS).

    There is no setting to change the style of widgets. IDLE currently uses ttk widgets when possible. It you edit the idlelib files at all extensively, I suggest you make a copy of idlelib so you can make a diff between the edited and original copies.
