If you have got a career into data analysis and work on machine learning projects, a solid understanding of NumPy is a mandate.
What is NumPy Python?
NumPy also known as ‘Numerical Python’ is a linear algebra library in Python.
It is one of the most basic and a power package for scientific computing and data manipulation in Python.
Most of the data science Python packages (Matplotlib, scipy, pandas, etc) use the ndarray objects to a greater extent.
Why is NumPy used?
It is a very important library when you speak of scientific computing with Python.
The powerful n- dimensional array object can be used as an effective multi dimensional container of generic data. Which otherwise couldn’t be done with the Python lists.
Numpy library is also used to integrate C/C++ and Fortran Code, perform basic numerical computations, create homogenous arrays, etc.
Using NumPy, mathematical and logical operations on arrays can be performed very conveniently.
These NumPy online courses will help you understand how and where these powerful libraries are put to use in an efficient way.
