It only executes once because you only call it once.

Your 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()

Change to something like:

def main():
    print "this program is crazy"
    while 1:
        x=input ('enter a number between 0 and 1 [-1 to exit]: ')
        if x == -1: break
        for i range (10)
            x=3.9*x*(1-x)
            print x

main()
