How to Split a Python List or Iterable Into Chunks

Splitting a Python list into chunks is a common way of distributing the workload across multiple workers that can process them in parallel for faster results. Working with smaller pieces of data at a time may be the only way to fit a large dataset into computer memory. Sometimes, the very nature of the problem requires you to split the list into chunks.

In this tutorial, you’ll explore the range of options for splitting a Python list—or another iterable—into chunks. You’ll look at using Python’s standard modules and a few third-party libraries, as well as manually looping through the list and slicing it up with custom code. Along the way, you’ll learn how to handle edge cases and apply these techniques to
