Real Python people are totally pragmatic about this - if you need performance, drop into C for critical routines and use Python to glue it all together. This is how NumPy works, you totally can do hard-core number crunching in Python and never need to actually know that it's C or FORTRAN under the hood!
Other language communities make a point of being self-contained and consider it a failure if you need to use a native method, but as ever, it's about the right tool for the job.
