Estimating genetics distance with python prgram

Question

[enrightnm]

Anyone written/used a python program to estimate genetic distance which allows you to input a nucleotide substitution model? I want to estimate divergence between sister taxa that have unequal sample sizes using an optimal model of substitution.

Thanks!

It is very easy in R. Google dist.dna

Fully aware of this APE function, but am trying to learn python code. Thank you for your response though :)
