# Get Median of Array with np.median Function of NumPy Library in Python (3 Examples)

In this tutorial youâ€™ll learn how to **apply the np.median function** in the Python programming language.

The tutorial consists of these topics:

Letâ€™s get started:

## Example Data & Libraries

First, we need to load the NumPy library.

import numpy as np # Import NumPy library

As a next step, weâ€™ll also have to define some data that we can use in the examples below:

my_array = np.array([[1, 2, 3], [4, 5, 6]]) # Create example array print(my_array) # Print example array # [[1 2 3] # [4 5 6]]

The previous output of the Python console shows the structure of our exemplifying data â€“ Itâ€™s a NumPy array containing six different values.

## Example 1: Median of All Values in NumPy Array

Example 1 explains how to calculate the median of all values in a NumPy array.

For this task, we can use the median function that is provided by the NumPy library:

print(np.median(my_array)) # Get median of all array values # 3.5

As you can see, the median of all values in our data is equal to 3.5.

## Example 2: Median of Columns in NumPy Array

In Example 2, Iâ€™ll illustrate how to compute the median for each column in our example array.

For this, we have to set the axis argument to be equal to 0:

print(np.median(my_array, axis = 0)) # Get median of array columns # [2.5 3.5 4.5]

## Example 3: Median of Rows in NumPy Array

Example 3 demonstrates how to find the median value for each row in our array.

For this, we have to specify axis equal to 1 within the median function:

print(np.median(my_array, axis = 1)) # Get median of array rows # [2. 5.]

## Video, Further Resources & Summary

Do you need further info on the Python code of this tutorial? Then I can recommend watching the following video instruction on my YouTube channel. In the video, I show the Python code of this article in a programming session.

Furthermore, you might want to have a look at some of the related tutorials on this website. I have released several posts already:
