Nope.  People have been telling me to use spaces in my Python for 
*years*, and I'm nowhere near assimilated.  The number of silly 
occasions where hitting <del> or <backspace> to remove a tab works where 
the editor doesn't pick up an attempt to remove 4-or-so-spaces keeps me 
going back to the simple "a tab is an indent" approach.  The simple fact 
( ;) I know, it's a holy war, there are no facts, but I feel like 
tweaking the spacies) is that having 3 or 4 or 2 or 8 characters 
represent the concept "indentation level" is just silly when you've got 
the single character representation available.

Oh, and decent editors (hint: PythonWin rules), that is, those based on 
Scintilla (almost every Python-specific IDE) *do* have a character for 
displaying <tab>, it's an elongated arrow that looks surprisingly like 
the arrow on my keyboard's tab key :) .  BTW the fact that I can set the 
display of an indentation level (tab) to whatever width I like is a 
*benefit* :) .

Of course, normally I just tell people telling me to switch "sure, I 
could change, but I have more Python code than you[1], so *you* conform" 
;) ,

[1] And, generally speaking, this is true, as anyone who has written 
more Python is almost certainly one of us old-timers and would never 
think of starting this silly thread *again*... :)
