How to print full array in Numpy?

Posted on April 30, 2021March 14, 2022 By Pythoneo

Let’s learn how to print the full array in the Numpy Python library. We are going to use a clever way to do that.

By default, Python will not print the whole array.

Setting threshold to print full array

There is a clever way to print the full array. To do that, you need to increase the np.set_printoptions threshold. To be sure the threshold will be enough, just set it as the size of your array. This is the optimal solution. 

import numpy as np

my_array = np.arange(10000).reshape(10, -1)

np.set_printoptions(threshold=np.size(my_array))

print(f"My fully printed array: \n {my_array}")

Using an infinity to print full array

The alternative method is to use np.set_printoptions(threshold=np.inf), which is positive infinity.

import numpy as np

my_array = np.arange(10000).reshape(10, -1)

np.set_printoptions(threshold=np.inf)

print(f"My fully printed array: \n {my_array}")
