NumPy is a popular Python library for data science that provides powerful and efficient tools for manipulating arrays. Arrays are collections of data elements that have the same type and shape ...

As noted above, NumPy arrays behave a lot like other Python objects, for the sake of convenience. For instance, they can be indexed like lists; arr[0] accesses the first element of a NumPy array.

only parts of an array are used (for example in distributed computation, in which each MPI node operates on a subset of the elements of the array) ...
