pyinstaller

PyInstaller is a command-line tool used to package Python programs into standalone executables that can be run on different platforms without the need for a Python interpreter or any dependencies. It analyzes the Python script, resolves dependencies, and bundles them together along with the Python interpreter into a single executable file.

PyInstaller supports Windows, macOS, and Linux platforms, and it can package Python programs into different formats such as executable files, single-folder distributions, or even self-extracting archives.

To use PyInstaller, you typically run it with the main Python script as an argument, and it will generate the executable file in the specified output directory. You can also customize the packaging process by using various command-line options or by creating a spec file that defines the packaging settings.

PyInstaller is commonly used for distributing Python applications that need to be run on systems without Python installed, or for simplifying the deployment process by packaging all the dependencies into a single executable.
