SciPy : Scientific Python
SciPy (pronounced "Sigh Pie" ) is an open-source collection of mathematical algorithms like minimization, Fourier transformation, regression , and other applied mathematical and scientific techniques. Many of the SciPy routines are Python "wrappers ", this means that Python routines that provide an interface for numerical and scientific libraries originally written in Fortran, C, or C++.
SciPy builds on the Python NumPy extention and is part of the NumPy stack. SciPy has optimized and added functions that are frequently used in NumPy, which provides convenient and fast N-dimensional array manipulation, and Data Science. SciPy adds numerical integration and optimization power to the interactive Python session by providing the user with high-level commands and classes for manipulating and visualizing data. Also, it is widely used by researchers across academia and industry, and has been used in the production of some major scientific results such as the LIGO gravitational wave detection , and the recent imaging of a black hole at the centre of galaxy M87 by the Event Horizon Telescope . As mentioned earlier, SciPy builds on NumPy N-dimensional array and therefore if you import SciPy in Python , there is no need to import NumPy.

Above code output how many cubic meters are in one liter.
You can find a large collection of mathematical and physical constants in scipy.constants. These SciPy constants can be helpful when you are working with Data Science projects.
Spatial data refers to data that is represented in a geometric space such as Triangulation, Voronoi Diagram and Convex Hulls of a set of points, by leveraging the Qhull library.
A Triangulation of a polygon is to divide the polygon into various triangles with which we can calculate an area of the polygon. Delaunay() Triangulation in Spatial Data is a method to generate triangulations through points.
