Then, close the file object once you have written all the elements of the list to it. We write to the text file using the write method of the file object. Each iteration of the for loop writes an element of the list months to the file. Using the Python open() built-in function we open a new file in write mode. In the first Python program, we will open a file object in write mode and then use a for loop to write each element in our data structure to the file: output_file = open('months.txt', 'w') Let’s have a look at how you can take the list of strings below and store each string in a text file using Python. This might be required, for example, if you store data in a file every time you run your application and that data can be available for later use the next time you run your application. Imagine you are building an application that has to persist a list of items after its execution. Let’s have a look at a few examples! Python Program to Write a List to a File in Python Using a Loop There are many scenarios in which writing the items of a list to a file can turn out useful. The file object needs to be opened in write mode. Then use a file object to write every element of the list to the file as part of each loop iteration. This tutorial will show you how to do that in multiple ways.Ī common approach to write list elements to a file using Python is to first iterate through the elements of the list using a for loop. Knowing how to write the elements of a list to a file in Python can be handy.
