How do I work with context managers

Context managers are a powerful feature in Python that allow for resource management and clean-up tasks. They ensure that resources are properly managed by automatically handling setup and teardown operations. The most common use of context managers is with the `with` statement, which helps manage file operations, database connections, and locks, ensuring proper closure and cleanup.

Here's a simple example of using a context manager to work with files:

with open('example.txt', 'r') as file:
            data = file.read()
            print(data)
        # File is automatically closed after this block

In this example, the file 'example.txt' is opened in read mode. The `with` statement ensures that the file is closed automatically after the block of code is executed, even if an exception occurs.
