I am beginning to learn python. I wrote the following module file to be imported into python, but the output in IDLE does not show anything. Please help
def main():
    print("This program illustrates a chaotic function")
    x=eval(input("enter a number between 0 and 1:"))
    for i in range(10):
        x=3.9*x*(1-x)
        print(x)
main() 
I used 
    import chaos 
command to import the module, but it doesn't show any output.



chaos.py(starting with lowercase and ending with.py?) Have you put it into the correct directory?
