By default, Python files (like almost all other) use the indentation
type configured in the preferences, which indeed defaults to tabs.

However, Geany 0.21 added the possibility to set filetype-specific
indent settings, so you can very well set the Python default indentation
to 4 spaces (which, by the way, is the example in the Python filetype).

Check the documentation, but basically create a filetypes.python in
~/.config/geany/filedefs/ and set the width and type key under the
indentation section:

> [indentation]
> width=4
> # 0 is spaces, 1 is tabs, 2 is tab & spaces
> type=0

It isn't the default to follow user's configuration, because changing
overrides requires (for now?) to edit the filetypes files, and because
Python actually works with tabs (unlike Makefiles as you noted).

Yes, that's a know issue, currently the indentation in the templates
isn't converted to the user's indentation, and the default templates all
use tabs.

Fortunately we already though about it and the Makefile filetype is
configured to use tabs-only by default :)
