[$] NumPy 1.20 has been released NumPy is a Python library that adds
an array data type to the language, along with providing operators
appropriate to working on arrays and matrices. By wrapping fast Fortran and
C numerical routines, NumPy allows Python
programmers to write performant code in what is normally a relatively slow
language. NumPy 1.20.0
was
announced on January 30, in what its developers describe as the largest
release in the history of the project. That makes for a good opportunity to
show a little bit about what NumPy is, how to use it, and to describe what's new in the
release.
