How to call a Python Class?

[David Shi]

I found a Python class within an Open Source software.
I would like to use it in my own Python script.
I tried to import it, but I got following message.
from intersection import *Traceback (most recent call last):  File "<pyshell#4>", line 1, in <module>    from intersection import *ImportError: bad magic number in 'intersection': b'\x03\xf3\r\n'
Can any one help?
Regards.
