How can I debug my code using contextlib in Python?

You can use the contextlib module to create context managers that help manage resources and debug your code effectively.

Can you give me an example of how to use it for debugging?

Sure! You can create a context manager that logs entry and exit points of a function. Here's a simple example:

from contextlib import contextmanager

@contextmanager
def debug_context(func):
    print(f'Entering {func.__name__}')
    yield
    print(f'Exiting {func.__name__}')

with debug_context(my_function):
    my_function()

What if I want to catch exceptions while debugging?

You can modify the context manager to catch exceptions. Here's how:

@contextmanager
def debug_context(func):
    try:
        print(f'Entering {func.__name__}')
        yield
    except Exception as e:
        print(f'Error in {func.__name__}: {e}')
    finally:
        print(f'Exiting {func.__name__}')
