How can I stay tab free in Geany on Ubuntu?
When I am coding in Python, tabs have always annoyed me. And the TAB is invisible. So strange.
When I open my code by gedit, those TABs are visible.
You are looking for 'soft tabs'

Edit > Preferences > Editor > Indentation > Type > Spaces
After changing the setting, close and reopen the file.
To apply the tab settings to every document in the current session, also click:
Project->Apply Default.
