-[componentize-py](https://github.com/bytecodealliance/componentize-py), respectively.
+A (non-exhaustive) list of other languages known to support components are:

+* Python through [componentize-py](https://github.com/bytecodealliance/componentize-py)

 for examples of how to build components using various languages.
 
 Other languages such as Ruby, etc, are hoped to be supported one day
 with `wit-bindgen` or with components in general. It's recommended to reach out

 a component is significantly different from how compiled languages currently
 work (e.g. Rust or C/C++). It's expected that the first interpreted language
