How do you display an entire array in python?
You won't always want all items printed, especially for large arrays. Show
A simple way to show more items:
It works fine when sliced array < 1000 by default. In this tutorial, we are going to learn how to print an array in Python. So before we get right into the topic, let us know a bit about Arrays in Python. Arrays are a collection of data elements of the same type under the same name. In Python, we can implement arrays using lists or the NumPy module. The NumPy module provides us with arrays of type Further, an array can be multi-dimensional. As we know, the simplest form of
multi-dimensional arrays is two-dimensional arrays. Hence, in this tutorial, we are going to be considering 1D as well as 2D Arrays. Now, let us look at some of the ways to print both 1D as well as 2D arrays in Python. Note: these arrays are going to be implemented using lists. Directly printing using the print() methodWe can directly pass the name of the array(list) containing the values to be printed to the But in this case, the array is printed in the form of a list i.e. with brackets and values separated by commas. arr = [2,4,5,7,9] arr_2d = [[1,2],[3,4]] print("The Array is: ", arr) #printing the array print("The 2D-Array is: ", arr_2d) #printing the 2D-Array Output: The Array is: [2, 4, 5, 7, 9] The 2D-Array is: [[1, 2], [3, 4]] Here, Using for loops in PythonWe can also print an array in Python by traversing through all the respective elements using Let us see how. arr = [2,4,5,7,9] arr_2d = [[1,2],[3,4]] #printing the array print("The Array is : ") for i in arr: print(i, end = ' ') #printing the 2D-Array print("\nThe 2D-Array is:") for i in arr_2d: for j in i: print(j, end=" ") print() Output: The Array is : 2 4 5 7 9 The 2D-Array is: 1 2 3 4 In the code above we traverse through the elements of a 1D as well as a 2D Array using for loops and print the corresponding elements in our desired form. Ways to print NumPy Array in PythonAs mentioned earlier, we can also implement arrays in Python using the NumPy module. The module comes with a pre-defined array class that can hold values of same type. These NumPy arrays can also be multi-dimensional. So, let us see how can we print both 1D as well as 2D NumPy arrays in Python. Using print() methodSimilar to the case of arrays implemented using lists, we can directly pass NumPy array name to the import numpy as np arr_2d = np.array([[21,43],[22,55],[53,86]]) arr = np.array([1,2,3,4]) print("Numpy array is: ", arr) #printing the 1d numpy array print("Numpy 2D-array is: ", arr_2d) #printing the 2d numpy array Output: Numpy array is: [1 2 3 4] Numpy 2D-array is: [[21 43] [22 55] [53 86]] Here, Using for loopsAgain, we can also traverse through NumPy arrays in Python using loop structures. Doing so we can access each element of the array and print the same. This is another way to print an array in Python. Look at the example below carefully. import numpy as np arr = np.array([11,22,33,44]) arr_2d = np.array([[90,20],[76,45],[44,87],[73,81]]) #printing the numpy array print("The Numpy Array is : ") for i in arr: print(i, end = ' ') #printing the numpy 2D-Array print("\nThe Numpy 2D-Array is:") for i in arr_2d: for j in i: print(j, end=" ") print() Output: The Numpy Array is : 11 22 33 44 The Numpy 2D-Array is: 90 20 76 45 44 87 73 81 Here also we print the NumPy array elements in our desired way(without brackets) by accessing the elements of the 1D and 2D array individually. ConclusionSo in this tutorial, we learned how to print an array in Python. I hope you now have a clear understanding of the topic.

How do you print a full list in Python?Using the * symbol to print a list in Python. To print the contents of a list in a single line with space, * or splat operator is one way to go. It passes all of the contents of a list to a function. We can print all elements in new lines or separated by space and to do that, we use sep=”\n” or sep=”, ” respectively.
How do I print all elements of a NumPy array?We can use the threshold parameter of the numpy. set_printoptions() function to sys. maxsize to print the complete NumPy array.
