fundamental aspect of the PEP 484 type system: when we annotate some variable with a type T, we are actually telling mypy that variable can be assigned an instance of T, or an instance of a subtype of T you have a class Child that inherits from Parent, then a value of type Child can be assigned to a variable of type Parent. For example, a RuntimeError instance can be passed to a function that is annotated normalize_id function above – mypy understands basic isinstance checks and so can infer that the user_id variable was of type int in the if-branch and of type str in the else-branch. As another example, consider

Release 23.11.1.dev1 Welcome to conda's documentation! Conda provides package, dependency, and environment management for any language. Here, you will find everything you need to get started using conda how the conda project is managed and how to contribute Development environment Follow this guide to get your own development environment set up 4.1 User guide 4.1.1 Concepts Explore the links to learn the packages in the Anaconda installer. The command conda create -n envname anaconda creates an environment that exactly matches what would be cre- ated from the Anaconda installer. You can create metapackages
