Summary

NumPy is the core Python library for numerical computing, most famous for its fast, memory-efficient, multidimensional arrays. Almost the entire Python data ecosystem like pandas, matplotlib, and scikit-learn is built on NumPy. This page is the gateway to all of the NumPy material in w3schools.

Key points

NumPy provides a hierarchy, a homogeneous data structure that is much faster than a regular Python list.
Arithmetic operations on an array are element-wise without the need for an explicit loop.
NumPy random modules provide a wide range of statistical distributions for simulation and data science.
The set of universal functions (ufunc) facilitates mathematical operations on the entire array at once.
