I haven't tried it, but that seems like it would be slow, because
Python would have to create a list, possibly hundreds of numbers long,
in RAM, every time you checked it. Unless Python caches them?

The traditional way I think is to use greater than and less than.

if (x>100) and (x<200) and (y>100) and (y<200):
   print "you clicked"
