Overview
NumPy is the short for Numerical Python. It provides data structures, algorithms and library glue needed for most scientific applications involving numerical data in Python. NumPy contains:
- A fast and efficient multidimensional array object
ndarray. For numerical data, NumPy arrays are more efficient for storing and manipulating data than other built-in Python data structures. - Functions for performing element-wise computations with arrays, and mathematical operations between arrays.
- Tools for reading and writing array-based datasets to disk.
- Linear algebra operations, Fourier transform, random number generation.
- A mature C API to enable Python extensions and native C or C++ code to access NumPy's data structures.
One of NumPy's primary uses is as a container for data to be passed between algorithms and libraries. NumPy is a dependency for Pandas.
