Python Launcher

This project provides a straightforward C# executable designed to simplify running Python scripts for end-users. It automatically handles the Python environment setup and dependency installation, abstracting away complexities like pip and virtual environments. The main goal launch scripts without installing python into system.

Features

  • Automatic Python Setup: Downloads and configures the latest stable Python (Windows x64 embeddable distribution) if not already present.

  • Self-Contained: Creates an isolated EmbeddedPython environment within the application's directory.

  • Dependency Management: Automatically installs Python package dependencies declared in your scripts using pip.

  • User-Friendly Installer: Includes an Inno Setup script for easy, wizard-based installation.

  • Isolated Execution: Runs Python scripts in separate console windows for clear output and interaction.

Getting started

Usage

  1. Install the Application:

    • Download PythonLauncher-Setup.exe.

    • Run the installer, which places the application files (including PythonLauncher.exe, install_deps.py and some other) into desired folder.

  2. Run Your Python Script:

    • Launch the installed PythonLauncher.exe via its Start Menu or desktop shortcut.

    • On first run, it automatically downloads and configures the latest Python environment.

    • When prompted, enter the full path or filename of your Python script (e.g., my_script.py if it's in the application's installed folder, or C:\Path\To\Your\script.py).

    • Dependency installation and your script will run in separate console windows.

Troubleshooting

  • "Access to the path 'C:\Program Files...' is denied.": The application was installed to a protected system directory. Solution: Run as administrator.

  • "Error: Could not determine the latest Python embed download URL.": Check internet connection. The Python FTP site structure or regex might need updating in program.cs.
