Py2Exe takes your Python code file and packages it into an executable file that you can distribute to a client that does not have Python installed. The executable file contains your byte code, all the required modules and the Python interpreter. It is not a small file.
The snippet is a template to run Py2Exe. For convenience, all the needed modification are done to the last line of the snippet. It is best to have this snippet, modified to accept your code file, and your code file in the same directory. Just follow the instructions in the remark section.
Note that Py2Exe only works with the Windows OS, and is freely available from:
