We can modify our code with the following: #open and read the file after the appending:Īfter checking the output, you will notice that writelines() does not add any line separators by default we have to specify the line separator. This method adds terms of a list in a programmatic way. Use writelines() to Add List Data to a FileĪnother method that you can use is writelines(). If you want to learn more on how to write files in Python with the write() method, check out our course on Working with Files and Directories in Python. It’s important to note that the parameters in the open() function will decide where the write() method will be active. We need to call the read() method, as shown below: Once this command has been executed, we want to read the file to see if it has been updated. We can then call the write() method to modify our file programmatically. The above line of code will open file.txt and will assign the file handler to the variable called file. This is the method we’ll use in this tutorial: It is shorter to use the with statement, as we do not need to call the close() method. However, with this method, you need to close the file yourself by calling the close() method: The first one is to use open(), as shown below:
The first step to write a file in Python is to open it, which means you can access it through a script.
There are multiple ways to write to files and to write data in Python. For more information, read How to Work with Files and Directories in Python and How to Rename Files with Python.

In this article, you will learn how to write to a file in Python.īefore diving into the nitty-gritty of how to write to file in Python, I want to mention that I use Python 3.8.5 and Windows 10.
