![]() ![]() We then created an index value, i, that we set to zero.We instantiated a list, numbers, that contains all of our numbers.Let’s see how we can use a Python while loop to iterate over each item in a list by taking a look at an example: # Using a Python While Loop to Iterate Over a List This means that the loop will continue to iterate until it is stopped. ![]() While a for loop is an example of definite iteration, a while loop is an example of indefinite iteration. In this section, you’ll learn how to loop over a list in Python using a while loop. How to Loop Over a List in Python with a While Loop In this case, we used the word number in order to make our code cleaner to write and to read. We’re able to loop over each item in the list by using any iterator name that we want to use. Let’s take a look at an example of how we can loop over a list of numbers in Python using a for loop: # Looping Over a List in Python with a For Loop This approach is intuitive because it loops over each item in the list (unless explicitly stopped). A for loop allows you to iterate over an interable object (like a list) and perform a given action. One of the simplest ways to loop over a list in Python is by using a for loop. Simplest implementation and easy for others to understandĬan iterate over multiple lists element-wiseĭifferent ways of iterating (or looping) over lists in Python How to Loop Over a List in Python with a For Loop To learn more about each of these methods, keep reading for a deeper dive. The table below breaks down the different methods in which you can loop over a list in Python. How to Iterate Over and Manipulate Python ListsĪ Guide to Iterating Over a List in Python.How to Iterate Over Multiple Python Lists Element-Wise.How to Iterate Over a List with enumerate.How to Iterate Over a List with Index Items Using Range.How to Loop Over a List in Python with a List Comprehension.How to Loop Over a List in Python with a While Loop.How to Loop Over a List in Python with a For Loop.A Guide to Iterating Over a List in Python.How to iterate and manipulate lists in Python.How to iterate over multiple lists in Python, and.How to enhance your iterating using the range() function and the enumerate() function.How to iterate over Python lists using for loops, while loops and comprehensions.Because of their versatility, knowing how to work with them is an important skill for a Pythonista of any level.īy the end of this tutorial, you’ll have learned: They’re also heterogeneous, meaning that they can hold many different data types. They are ordered and indexable, meaning that their order matters and that you can access items based on their order. Python lists are one of the cornerstone data structures in the language. Given that there are many different ways of accomplishing this, it can be helpful to understand which method to use. What’s more, is that you’ll learn when each of these methods is the best method to use. You’ll learn how to iterate with for loops, while loops, comprehensions, and more. In this tutorial, you’ll learn how to iterate (or loop) over a list in Python. ![]()
