What are some examples of using contextlib.resources in Python?

The contextlib.resources module in Python provides utilities for managing resources. Would you like to see a specific example?

Yes, can you show me how to use it to manage file resources?

Sure! You can use contextlib.resources to open files safely. Here's a simple example:

from contextlib import closing, resources

with resources.open_text('example.txt') as f:
    data = f.read()
    print(data)

What happens if the file doesn't exist?

If the file doesn't exist, a FileNotFoundError will be raised. You can handle this using a try-except block.

Can you provide an example of that?

Certainly! Here's how you can handle the exception:

try:
    with resources.open_text('non_existent_file.txt') as f:
        data = f.read()
except FileNotFoundError:
    print('File not found!')
