As much as I like scikit-learn and pandas, Python likely won't be replacing my R code for quite some time, and I'll continue to hop between the two of then. R is, first and foremost, a language for statistical analysis, and that's really where it shines. Python is getting better (it used to be "you want to do...what?"), but it doesn't have nearly the package infrastructure R does for advanced statistics. It is, for most statistical computing tasks not even on the radar for a number of my colleagues.
