set-package-attribute

Run modules inside packages as scripts. Automatically sets the __package__ attribute of any script which imports it and calls the initialization function set_package_attribute.init(). This allows the script to use explicit relative imports, which fail otherwise.

For full documentation, see https://abarker.github.io/set-package-attribute.

Also available on PyPI for installation with pip.

Brief usage summary

To use the package just import it before any of the non-system files, inside any module that you might want to run as a script, and call the init function. These statements should be inside a guard conditional, so that they only run when the module is executed as a script:

if __name__ == "__main__":
    import set_package_attribute
    set_package_attribute.init()

The guard conditional is not required if the module is only ever run as a script, i.e., if it is never imported by any module. The init function must be called before any explicit relative imports, and before importing any modules from within the same package which themselves use such imports.

If you are happy with the default init arguments then there is a shortcut import which automatically calls init for you:

if __name__ == "__main__":
    import set_package_attribute_magic
