Using python is great; your deduction about use of OO in R harder to
support. The Bioconductor project (300+ packages, not all with strong
OO components) makes extensive use of S4, as does the Matrix
recommended package, for instance; S4 really opens the door to more
complex OO approaches, but a very large number of packages use OO
concepts under the S3 object system.
