Importing a module

[snippsat]

All you do is delete the spaces in front of the text. In your code you had
main()
which has 8 spaces in front of it. Just delete them

Can also delete main() all together,dos not need that call when import it.

# File: chaos.py
# A simple program illustrating chaotic behavior.
def main():
   print("This program illustrates a chaotic function")
   inp = float(input("Enter a number between 0 and 1: "))
   for i in range(10):
       inp = 3.9 * inp * (1 -inp)
       print(inp)

Test import:

Output:
>>> import chaos
>>> chaos.main()
This program illustrates a chaotic function
Enter a number between 0 and 1: .5

Look a little at at if __name__ == '__main__': and what it does.
