Generate Self-Contained Executables from Python Projects Without Installing Python

Overview

In this article, we delve into various methods for creating self-contained executables from Python projects, enabling users to run them without Python's presence on their systems.

Freeze-Style Programs

The foremost approach is using "freeze" programs like PyInstaller, cx_Freeze, py2exe, and py2app. These tools bundle Python with the project, creating a single executable. However, the created executable will only be compatible with the operating system on which it was generated. If multi-platform compatibility is desired, virtual machines or Wine can be considered.

PyInstaller and cx_Freeze

PyInstaller supports Python versions 3.7-3.10 on Windows, Mac, and Linux. cx_Freeze has similar compatibility.

py2exe and py2app

py2exe only supports Windows for Python versions 3.7-3.10. py2app is exclusive to Macs, supporting Python versions 3.6-3.10.

pynsist

As an alternative to bundling Python, pynsist creates Windows installers that install Python on the user's system. It requires Python 3.5 to run but supports bundling any Python version. It can be executed from Windows, Mac, and Linux.

Nuitka and Cython

Nuitka compiles Python code into an executable, while Cython compiles it to C. Both require C compilers and support various Python versions on Windows, Mac, and Linux. These tools claim performance improvements but typically take longer to generate executables compared to freeze-style programs.

Conclusion

While there are various options for creating executables from Python projects, the selection depends on factors such as desired platform, Python version requirements, and performance considerations. Freeze-style programs provide a straightforward solution, while pynsist and Nuitka offer alternative approaches with potential advantages.
