devel/py-lazy_imports 1.2.0 DragonFly

This python utility package helps to create lazy modules. A lazy module defers loading (some of) its attributes until these attributes are first accessed. The module's lazy attributes in turn are attributes of other modules. These other modules will be imported/loaded only when (and if) associated attributes are used. A lazy import strategy can drastically reduce runtime and memory consumption.

Additionally, this package provides a utility for optional imports with which one can import a module globally while triggering associated import errors only at use-sites (when and if a dependency is actually required, for example in the context of a specific functionality).
