If you want the long answer, search DejaNews for "space tab".  Short
answer: it makes programs easier to read.  If you're concerned about
mixing tabs and spaces, use -tt on the Python command line.

After 1.5 years, I still find it annoying to use whitespace to indicate
program blocks (particularly when rearranging code), but I find the
readability more than compensates.  Note that many people here will tell
you to use an editor that makes this easier.

>2. Why variable doesn't have to be declared before use?

This usually ends up being less of a problem in Python because functions
and modules tend to be shorter.  But, yes, this is a concern that a lot
of people have; however, it probably will not get addressed soon.
