Geometric Mean in Python (Example)

This tutorial illustrates how to compute the geometric mean in Python programming.

The post consists of this information:

Let’s do this!

Example Data & Add-On Libraries

I’ll use the data below as a basis for this Python tutorial:

my_list = [4, 3, 8, 7, 8, 4, 4, 1, 5]    # Create example list
print(my_list)                           # Print example list
# [4, 3, 8, 7, 8, 4, 4, 1, 5]

The previous output of the Python console shows that our example data is a list object containing nine integers.

Example: Get Geometric Mean Using gmean() Function of SciPy Library

In this example, I’ll demonstrate how to calculate the geometric mean of a list in Python.

For this task, we first have to import the gmean function of the SciPy library:

from scipy.stats import gmean            # Import gmean function of SciPy library

In the next step, we can apply the gmean function to our example list to get the geometric mean:

print(gmean(my_list))                    # Apply gmean function
# 4.226198741306655

As you can see, the geometric mean of the numbers in our list is 4.22.
