What is Numpy?
NumPy is a library for the Python programming language, adding support for large, multi-dimensional arrays and matrices, along with a large collection of high-level mathematical functions to operate on these arrays.
How are Lists different from Numpy?
<1> Faster to read less bytes of memory
Numpy: fixed type, e.g. Int32
List: Size, Reference Count, Object Type, Object Value
<2> Continuous memory
So for usage
Application of Numpy:
<1> Mathematics(MATLAB Replacement)
<2> Plotting (Matplotlib)
<3> Backend(Pandas, Connect 4, Digital Photography)
<4> Machine learning
