How do I use context managers when working with files in Python?

You can use the with statement to create a context manager for file operations. It ensures proper resource management.

Can you show me a simple example?

Sure! Here's a basic example:

with open('file.txt', 'r') as file:
    content = file.read()
    print(content)

This automatically closes the file after the block.

What happens if an error occurs while reading the file?

If an error occurs, the context manager still ensures that the file is closed properly, preventing resource leaks.

Are there any other benefits of using context managers?

Yes, they help in managing resources like network connections and database connections, making your code cleaner and safer.
