how to make a python or perl script portable to both linux and windows?

Question

I was wondering how to make a python script portable to both linux and windows?

One problem I see is shebang. How to write the shebang so that the script can be run on

Answer 1

The shebang line will be interpreted as a comment by Perl or Python. The only thing that assigns it a special meaning is the UNIX/Linux shell; it gets ignored on Windows. The way Windows knows which interpreter to use to run the file is through the file associations in the registry, a different mechanism altogether.
