zipapp module allows us to create self-contained Python standalone programs that can be distributed to users who have Python already installed on their system.
Python packages not using C extensions can be bundled as well. shiv is recommended for those applications using those kind of extensions. In general, if your dependencies don't require a C compiler, you should be good to go using zipapp module.
Directory structure for source code:
/tmp/listd ᐅ tree
.
├── listdir
│ ├── __main__.py
│ └── listdir.py
└── requirements.txt
Where listdir/__main__py contains the following lines:
import listdir
listdir.run()
And listdir/listdir.py these lines:
from shell_cmd import sh
def run():
print(sh("ls -l"))
Finally requirements.txt contains this line:
shell-cmd==1.0.2
python -m pip install -r requirements.txt --target listdir
rm -rf listdir/*.dist-info
rm -rf listdir/**/__pycache__
python -m zipapp listdir
The final listdir.pyz is ready for distribution and you can execute it using the following command:
python listdir.pyz
It's possible to specify the interpreter as the command to run. This means you can invoke directly to the standalone:
python -m zipapp -p "/usr/bin/env python" listdir
./listdir.pyz
