# How to compute the covariance matrix of two Pandas DataFrame columns using Python

• 1 minThe covariance is a widely used statistical estimate to measure how much a variable does vary when the other increase or decreases.

Here is an example of when you plot two variables.

The covariance is also used to compute the correlation between two variables.

The Pandas library provides the **DataFrame.cov()** method that will compute the covariance for you.

## Here is the code

Here you are! You should be by now the king of covariance in Python!
