## Best Python Libraries for Machine Learning

### NumPy

NumPy is a free, open-source Python scientific computing package. It processes arrays and matrices. **Here are some of the key features of Numpy.**

- high-performing N-dimensional array object: The homogeneous array object is NumPy library's most critical feature. Numpy supports both one- and multi-dimensional arrays.
- one dimensional array: it consists of a single row or column and the elements within are homogeneous in nature.
- multidimensional: it consists of serval rows or columns where each column is a dimension. Similar to Microsoft Excel, the elements are homogeneous.

- C/C+ and Fortran code integration tools: NumPy functions work with code from other languages, and as such, it easily integrates functionalities available in other programming languages.
