+# getitem
+
+A project showcasing how to create a `__getitem__` override that also showcases how to deal with multiple incoming types
+
+## Relevant Documentation
+
+Some of the relevant documentation links for this example:
+
+* Converting Slices to Indices: https://docs.rs/pyo3/latest/pyo3/types/struct.PySlice.html#method.indices
+* GetItem Docs: https://pyo3.rs/latest/class/protocols.html?highlight=__getitem__#mapping--sequence-types
+* Extract: https://pyo3.rs/latest/conversions/traits.html?highlight=extract#extract-and-the-frompyobject-trait
+* Downcast and getattr: https://pyo3.rs/v0.19.0/types.html?highlight=getattr#pyany
+
+
+## Building and Testing
+
+To build this package, first install `maturin`:
+
+```shell
+pip install maturin
+```
+
+To build and test use `maturin develop`:
+
+```shell
+pip install -r requirements-dev.txt
+maturin develop
+pytest
+```
+
+Alternatively, install nox and run the tests inside an isolated environment:
+
+```shell
+nox
+```
+
+## Copying this example
+
+Use [`cargo-generate`](https://crates.io/crates/cargo-generate):
+
+```bash
+$ cargo install cargo-generate
+$ cargo generate --git https://github.com/PyO3/pyo3 examples/decorator
+```
+
+(`cargo generate` will take a little while to clone the PyO3 repo first; be patient when waiting for the command to run.)
