You indented the wrong thing.  You put your if/else statement in a
non-standard way (which works, but is discouraged).  Also, you ended
the first line with a semicolon (same case).  So, the proper code
would be:

a=3D1
if a=3D=3D1:
    print(1)
else:
    print(0)
wait =3D input("press key")

(I resisted the urge to add spaces around `=3D` and `=3D=3D`, something mos=
t
people want you to do.)
