Is there a direct function in Python Igraph to do S-core decomposition on weighted graphs?

No, there is not. You are welcome to open a feature request [for the C core of igraph](https://github.com/igraph/igraph/issues/new/choose) and fill out all details, including use cases, existing algorithms, references, and anything else that may be helpful for implementing it.
