In coding, files are used to store data. Then you can easily access that data at any point. Reading, writing, and editing files in Python is a common task, since the language provides us with built-in functions that allow us to do so. In this article, I'll create a simple project where I'll write to, append to, and then finally at the end read from a text file in Python to show you how it's done. You can follow along with me and go through the same steps I do. Let's
get started! The first step is to set up the project's directory structure. Choose a place where you want to create a new directory and follow the steps below. I am creating the project in my home directory. At the moment, the text file is empty: Let's add something to it. The best practice for writing to, appending to, and reading from text files in Python is using the The general syntax looks like this:
Breakdown:
So, to add some text to the text file, in
To add the text on different lines, like I have done in the example above, you have to explicitly add in the newline character, Open the built-in terminal in Visual Studio Code ( Check out It's important to note that each time you use the Let's say I already had some dummy text in my If I run the previous code:
It will now look like this: I have lost all my previous data. How to append a text file in PythonAppending works similarly to writing. But this time, you open the text file for appending, with the parameter for the mode in the
Whatever goes in the So, to add some more text to
After running the code again, The previous text doesn't get erased. The new text gets added immediately after the old, and you again have to explicitly add in a newline character:
How to read from a file in PythonTo read from a file, you again use the For
opening text files, the mode is Then, the
Output: To read from a file in Python, you could also create a
Output: With this way, each line is printed out separately. ConclusionThis article showed you some simple examples of how to write, edit, and read from files in Python.
