I do for the following reason: If you use only tabs for leading
whitespace you loose the ability to align things. Here's and example
using a list (view using a fixed width font):

lst = [1, 2, 3
       4, 5, 6]

This definition uses alignment to align the first element on the first
line with the first element of the second line. You can't do this kind
of alignment using tabs.

Yes, most people use that style or its variations (e.g. when multiple assignments have the equal sign aligned somewhere in the middle of a line or comments are aligned at the end, etc). I do not because when I rename lst to myLst then I need to modify two lines (the second one to fix the alignment). Also I do not like that the change looks bigger in a text diff. I prefer:

lst = [1, 2, 3
  4, 5, 6]  -- fixed indent by two spaces regardless of previous lines

Or, if I really care about alignment at such a low level (which I almost never do):

lst =
  [1 ,2 ,3   -- fixed indent by two spaces
  ,4 ,5 ,6]  -- fixed indent by two spaces

For your style spaces are the only way to go, what I'm perfectly fine with. Actually whatever way this is resolved, I do not care. Just wanted to point out that there is a use for tabs at the line start ... now thinking it might have been an error :-)
