How can I improve performance in Python using contextlib?

You can use contextlib to create context managers that help manage resources efficiently, reducing overhead.

Can you give me an example of a context manager using contextlib?

Sure! Here's a simple example:

from contextlib import contextmanager

@contextmanager
def my_context():
    print('Entering the context')
    yield
    print('Exiting the context')

with my_context():
    print('Inside the context')

How does this improve performance compared to traditional methods?

Using contextlib allows for cleaner code and automatic resource management, which can lead to fewer memory leaks and better performance.

Are there any performance benchmarks comparing contextlib with other methods?

Yes, there are benchmarks available that show contextlib can be more efficient in managing resources compared to manual handling.
