How to Create a Single Executable from a Python Script using py2exe?

Creating a Single Executable File with py2exe

py2exe is an invaluable tool that allows developers to convert Python scripts into standalone Windows executables. It offers a unique feature known as "bundle_files" that enables the generation of a single executable file, eliminating the need for extracting and running multiple files.

The "bundle_files" Option

The "bundle_files" option in py2exe's setup.py configuration file controls whether and how the distribution files are bundled with the executable. Setting it to 1 will bundle everything, including the Python interpreter.

Setting up the Executable

To create a single-file executable, follow these steps:

• Set bundle_files to 1: Indicate that everything should be bundled into the executable.
• Set compressed to True: Compress the bundled files for efficient distribution.
• Set zipfile to None: Prevent the creation of an additional library.zip file.

Sample Setup.py

Here is a sample setup.py file that demonstrates these settings:

from distutils.core import setup
import py2exe, sys, os

sys.argv.append('py2exe')

setup(
    options = {'py2exe': {'bundle_files': 1, 'compressed': True}},
    windows = [{'script': "single.py"}],
    zipfile = None,
)

By implementing these settings, you can use py2exe to effortlessly generate a single executable file that will run your Python script.
