What are the differences between contextlib and try-except in Python?

Contextlib is a module that provides utilities for working with context managers, while try-except is a block for handling exceptions.

Can you give me an example of how to use contextlib?

Sure! You can use contextlib to create a context manager using the contextmanager decorator. 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 compare to using try-except?

Using try-except is more about handling exceptions that may occur during execution. For example:

try:
    risky_operation()
except Exception as e:
    print(f'An error occurred: {e}')

When should I use contextlib instead of try-except?

Use contextlib when you need to manage resources or setup/teardown actions, while try-except is for error handling.
