1.3. Module Zipapp

1.3.1. `zipapp`

Python has been able to execute zip files which contain a __main__.py file since version 2.6
In order to be executed by Python, an application archive simply has to be a standard zip file containing a __main__.py file which will be run as the entry point for the application

1.3.2. Creating Standalone Applications

Create your application in a directory "myapp" as normal
Create __main__.py file (this will be entrypoint)

Install (using pip) all of your application's dependencies:

$ python -m pip install -r requirements.txt --target myapp

Package the application using:

$ python -m zipapp -p "/usr/bin/env python3" myapp

1.3.3. About Standalone Applications

This will produce a standalone executable
It can be shipped to users as a single file
It can be run on any machine with the appropriate interpreter available
On Unix, the myapp.pyz file is executable as it stands
If you want you can rename the file to remove the .pyz extension
On Windows, the myapp.pyz[w] file is executable by virtue of the fact that the Python interpreter registers the .pyz and .pyzw file extensions when installed

1.3.4. Run archive

$ python myapp.pyz
