Which library can be used to create your own Python bindings given a custom YANG module?

The library that can be utilized to create your own Python bindings based on a custom YANG module is Ydk-gen. This tool is specifically designed for code generation, allowing developers to generate Python representations of their defined YANG models. By using Ydk-gen, developers can take custom YANG modules and produce the appropriate Python bindings that enable interaction with network devices according to their defined service model.

Other options, such as Ydk-py, are used for using existing generated bindings in Python applications but do not assist in the generation of bindings from YANG modules. Ydk-yang and Ydk-pyang serve different purposes; Ydk-yang is typically involved with handling YANG data models, while Ydk-pyang is more focused on validating YANG modules against the YANG model specifications. The key differentiator for Ydk-gen is its specific functionality to create Python bindings from custom-defined YANG modules, which is essential for integrating network programmability solutions.
