def main():
    a = 3
    b = 5
    print( "a+b=", a+b )

main()

# -----------------------------------------
# program2.py

print( "hello!" )
def main():
    a, b = 3, 5
    print( "a+b=", a+b )

main()

# -----------------------------------------
# program3.py

print(  "hello!" )
def main():
    a, b = 3, 5
    print( "a+b=", a+b )
print( "bye!"

main()

# -----------------------------------------

print( "hello!" )
def main():

    print "a+b=", a+b
    print "bye!"

# -----------------------------------------
# program5.py

a = 7
 
def main():
    a, b = 3, 5
    print( a , '+', b, '=', a+b )
 
print( a )
 
main()


# -----------------------------------------
