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 one of the most important foundational packages for numerical computing in Python and a dependency for Pandas.

NumPy does not provide time series manipulation, which is present in Pandas.
