Python – Split Array or List to chunks

Today in this article, we shall see how to perform Python Split Array or List to chunks i.e. evenly sized chunks.

Python has a very simple way of achieving the same.

In fact, there are numerous ways you can achieve this but we shall concentrate on simple basic techniques in this article.

Today in this article, we will cover below aspects,

Command – Python Split Array or List to chunks 

[list[i:i+x] for i in range(0, len(list), x)]

Create as Reusable Method

def chunk_list (x):
    return [list[i:i+x] for i in range(0, len(list), x)]

Example

list = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16,18,19,20]
 def chunk_list (x):
    return [list[i:i+x] for i in range(0, len(list), x)]
 print(chunk_list(5))

Output

[[1, 2, 3], [4, 5, 6], [7, 8, 9], [10, 11, 12], [13, 14, 15], [16, 17, 18], [19, 20]]

Using range to loop and Chunk array

The range type represents an immutable sequence of numbers on the fly and is commonly used for looping a specific number of times in loops.

The numbers can be used to index into collections such as strings.

Command

• range(stop)

• range(start, stop[, step])

In the above command

start- The value of the start parameter (or 0 if the parameter was not supplied)

stop – The value of the stop parameter

step – The value of the step parameter (or 1 if the parameter was not supplied)

Example 1

range(3, 6)

Create a sequence of numbers from 3 to 5, and print each item in the sequence

Output

3

4

5

Example 2

range(5, 25, 5)

Create a sequence of numbers from 5 to 25, but increment by 5

Output

5
10
15
20

That’s all! Happy coding!
