Binary package “python-numpy” in ubuntu bionic

Numerical Python adds a fast array facility to the Python language

 Numpy contains a powerful N-dimensional array object, sophisticated
 (broadcasting) functions, tools for integrating C/C++ and Fortran
 code, and useful linear algebra, Fourier transform, and random number
 capabilities.
 .
 Numpy replaces the python-numeric and python-numarray modules which are
 now deprecated and shouldn't be used except to support older
 software.
