How to Close a File in Python Using a Statement?

Estimated read time 1 min read

To close a file in Python using a statement, you can use the with statement, also known as a context manager. The with statement automatically takes care of closing the file, even if an exception occurs. Here’s an example:

with open("example.txt", "w") as file:
    file.write("Hello, World!")
    # Perform other operations with the file if needed

# File is automatically closed outside the 'with' block

In this example, we open a file named “example.txt” in write mode using the open() function within a with statement. The file object is assigned to the variable file.

You can perform any file operations within the with block, such as writing, reading, or appending data to the file. Once the block is exited, the file is automatically closed, regardless of whether an exception occurred or not. This ensures that the file is properly closed and system resources are freed.

Using the with statement is the recommended approach for file handling in Python as it provides automatic resource management and simplifies the code by eliminating the need to explicitly call the close() method.
