very very basic question

[aghazalp]

thanx george for the prompt answer... when you say add a call that
means what exactly?...here is the program I was supposed to
write...could you tell me what to add where in this program?

def main():
    print "this program is crazy"
    x=input ('enter a number betwenen 0 and 1: ')
    for i range (10)
    x=3.9*x*(1-x)
    print x

main()


thanx again
