Vendy is a tool for vendoring third-party packages into your project.

Disclaimer:

This is not an officially supported Google product.

Example:

In a pyproject.toml file in the root of your package, define the target directory (should be in the same directory as the pyproject.toml file), and the packages to vendor:

[tool.vendy]
target = 'my_project'
packages = [
    "sampleproject==1.2.0",
]

On the command line:

$ python -m vendy

Result:

$ tree
.
├── my_project
│   ├── __init__.py
│   └── _vendor
│       ├── bin
│       │   └── sample
│       ├── my_data
│       │   └── data_file
│       ├── sample
│       │   ├── __init__.py
│       │   └── package_data.dat
│       └── sampleproject.LICENSE.txt
└── pyproject.toml

And you can import from the vendored library like:

-from sampleproject.foo import bar
+from myproject._vendor.sampleproject.foo import bar
