将模块文件导入python

Question

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.

Answer 1

-------chaos.py----------

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)

-------fileimport.py---------

import chaos
chaos.main()

Note Both these files should be in same directory

Parent Folder
