oops try again, the_flying_circus() returned the value None, did you forget to add return statement?
# Make sure that the_flying_circus() returns True def the_flying_circus(): if not (2<3) and 1<2: # Start coding here! print "this really is true" # Don't forget to indent # the code inside this block! elif 2<3: print "that is true." # Keep going here. # You'll want to add the else statement, too! else: print "None of the above."
