Numpy : The linear algebra library in Python for data science

NumPy (Numerical Python) is a linear algebra library in Python. It is a very important library on which almost every data science or machine learning Python.

NumPy is very useful for performing mathematical and logical operations on Arrays. NumPy Arrays come in two forms; Vectors and Matrices. Vectors are strictly one-dimensional(1-d) arrays, while Matrices are multidimensional. In some cases, Matrices can still have only one row or one column.

Linear algebra is the branch of mathematics concerning linear equations such as:

linear maps such as:

and their representations in vector spaces and through matrices.
