Is there any method or way to get hazard ratio?

We are using Pycox - CoxPH Model to find out hazard ratio of each genetic mutations.
So, we put presence of each genetic mutations as 1 or 0 in x, survival time and event in y.

We want to get hazard ratio of a particular genetic mutation.
Is there any method or way to get it?

Start by reviewing the Pycox CoxPH Model API and its handling of mutation indicators in x, survival time, and event values. Determine whether the model already exposes hazard ratios and what documentation or API change would be needed; done should be a clearly documented way to obtain the ratio for a particular mutation.
