Yes, of course. Things like numpy are far from new and in many cases are easy to use wrappers around the real computational workhorses written in, say, Fortran or C. For example, check out lapack https://hpc.llnl.gov/software/mathematical-software/lapack which is still, as far as I know, the gold standard.
Python is widely adapted not really because the language itself is any good or particularly performant (it's not at all), but because it presents easy to use wrapper APIs to developers who may have a poor background in Computer Science, but are rather stronger in statistics, general data analysis, or applied fields like economics.
