How to Get the Variance of a List in Python?

This article shows you how to calculate the variance of a given list of numerical inputs in Python.

In case you’ve attended your last statistics course a few years ago, let’s quickly recap the definition of variance: it’s the average squared deviation of the list elements from the average value.

So, how to calculate the variance of a given list in Python?

Python 3.x doesn’t have a built-in method to calculate the variance. Instead, use any of the following to methods:

With External Dependency: Import the NumPy library with import numpy as np and use the np.var(list) function. Without External Dependency: Calculate the
