    No, a tab isn't a tab.

    As you just said, "You should be able to configure your editor to display
tabs..."  Oh, so a tab isn't a tab.  I like indention of 4 so my tab is 4
spaces.  You like 8 so yours is 8 spaces.  A tab is not a tab.  A tab is a
collection of spaces, visually.

    Now, if you had read my post you would have seen where your whole "a tab
is a tab" bubbub breaks down.  Here it is AGAIN since you missed it the first
time.

some_dict = {'Jane':{'Age':'21', 'Dept':'0001', 'Ext':'1234'},
             'John':{'Age':'22', 'Dept':'0010', 'Ext':'5678'},
             'Jeff':{'Age':'23', 'Dept':'0100', 'Ext':'9009'},
             'Jody':{'Age':'24', 'Dept':'1000', 'Ext':'8765'},
             'Jeny':{'Age':'25', 'Dept':'0110', 'Ext':'4321'}
            }

    With spaces that always comes out the same.  With tabs set to different
lengths you get different results.  The only constant when it comes to
indention is a space.  A space is a space.  A tab is not constant and
therefore should NOT be used for indention.  Ever.

    Indention isn't about preference, it is about making the code readable.
And as the above example shows, readable code could be rendered unreadable by
tab "preferences".
