How to Create a Single Executable File from a Python Script Using py2exe?

How to Generate Single Executable File with py2exe

In computing, a single executable file is a program that can be directly executed without the need for additional dependencies or installation. It contains all the necessary code and resources to run the program. One way to generate a single executable file in Python is through py2exe.

Using py2exe's bundle_files Option

To create a single executable file using py2exe, utilize the bundle_files option in your setup.py file. Set bundle_files to 1, specify compressed as True, and set zipfile to None. This instructs py2exe to bundle all files, including the Python interpreter, into a compressed single file for distribution.

As explained by py2exe documentation, valid values for bundle_files include:

• 3 (default): Don't bundle files
• 2: Bundle everything except the Python interpreter
• 1: Bundle everything, including the Python interpreter

By setting zipfile to None, the bundled files are incorporated into the executable instead of a separate library.zip archive.

Sample Setup.py File

Here's a sample setup.py file demonstrating the bundle_files configuration:

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,
)

When executed, this setup.py file will generate a single executable file (single.exe) that includes the Python interpreter and all necessary files to run the single.py script.
