What is the best way to find deltalake version on OSS and Databricks at runtime?

To identify certain deltalake features available on a certain installation, it is important to have a robust way to identify deltalake version. For OSS, I found that the below Scala snippet will do the job.

import io.delta
println(io.delta.VERSION)

Not sure if there is an equivalent method in Python to get the version at runtime. I am not after something like pip show deltalake.

Anyway, the other aspect is that the above snippet on Databricks returns a strange value. For example on DBR 12.0, I got 1.1.0 which does not match 2.2.0 version published on DBR 12.0 release notes page.

I know that deltalake on Databricks does not necessarily have to match a certain OSS version (at lease before open sourcing delta).

@Yousry Mohamed - could you please check the DBR runtime release notes for the Delta lake API compatibility matrix section ( DBR version vs Delta lake compatible version) for the mapping.
