print statement in lambda expression

[Michael P. Soulier]

    Hello people. 

    I just recently found that I couldn't put a print statement in a lambda
expression as a binding in Tk. Could someone explain why? 

    ie.
    
    b1 = Button(frame, text="Message", command=lambda: print "message")

    If I replace print with sys.stdout.write, it works fine. I don't follow
why. 

    Thanks,

    Mike
