Array programming with NumPy | Nature | 9/16/2020

Now, 15 years later, NumPy underpins almost every Python library that does scientific or numerical computation8,9,10,11, including SciPy12, Matplotlib13, pandas14, scikit-learn15and scikit-image16. NumPy is a community-developed, open-source library, which provides a multidimensional Python array object along with array-aware functions that operate on it. Because of its inherent simplicity, the NumPy array is the de facto exchange format for array data in Python.
