How To Print A File In Python

by

In this blog post, we’ll learn how to read and print the contents of a file using Python. This is a simple but essential operation when working with files and performing file-related tasks.

Opening a File in Python

Before we can print a file’s contents, we need to open the file. To open a file in Python, we use the built-in open function. The open function takes two arguments: the file path and the file mode. The file mode can be either ‘r’ for reading, ‘w’ for writing, or ‘a’ for appending. By default, the mode is set to ‘r’.

Let’s assume we have a file called example.txt with the following content: 

This is an example file.
It contains three lines of text.
Now you know how to open a file in Python!

To open the file, we can use the following code:

file = open(“example.txt”, “r”)

Reading and Printing a File’s Contents

Once we have the file open, we can read its contents using various methods. The most common methods are read, readline, and readlines. In this post, we’ll focus on using the read method, which reads the entire contents of the file.

After reading the file’s contents, we can print them using the print function. Here’s the complete code to open, read, and print the contents of our example file:

file = open(“example.txt”, “r”)
contents = file.read()
print(contents)
file.close()

This code will output the following: 

This is an example file.
It contains three lines of text.

Using a Context Manager

It’s essential to close the file after performing any file operation to avoid any potential issues. In the previous example, we used the close method to close the file. However, it’s recommended to use a context manager, which automatically closes the file once the block of code is executed. We can use the with statement to create a context manager, like this:

with open(“example.txt”, “r”) as file:
contents = file.read()
print(contents)

This code will produce the same output as before but ensures that the file is closed automatically, even if an error occurs during the file-reading process.

Conclusion

In this blog post, we learned how to open, read, and print a file’s contents in Python. We also discussed the importance of closing a file after performing file operations and how to use a context manager to do so automatically. Now you know how to print a file in Python, a crucial skill when working with files and performing file-related tasks.
