If you take a look at your if-cases, you see that a lot of strings in
there are the same. The code is therefore redundant, and this is what
can be trimmed down.

Consider this code:

if var1 = 1 and var2 = 0:
  print "Var1 is 1, var2 is 0"
if var1 = 0 and var2 = 0:
  print "Var1 is 0, var2 is 0"
if var1 = 1 and var2 = 1:
  print "Var1 is 1, var2 is 1"
if var1 = 0 and var2 = 1:
  print "Var1 is 0, var2 is 1"

This scope is redundant in a lot of ways and can be trimmed down to
one if and one print:

if (var1 in [0,1]) and (var2 in [0,1]):
  print "Var1 is %d, var2 is %d" % (var1, var2)

Your code is similiar to the above. It takes time to learn how to trim
down redundant code. Vast knowledge of a language itself is not
required, but a pretty solid knowledge about the basics is probably
required. If you are entirely new to programming, it might be
cumbersome though.

Give it a try, and don't hesitate to ask again.
