How does exception handling work in context managers?

In Python, context managers handle exceptions using the __exit__ method. If an exception occurs, this method can manage it.

Can you give me an example of a context manager with exception handling?

Sure! Here's a simple example:

class MyContextManager:
    def __enter__(self):
        return self
    
    def __exit__(self, exc_type, exc_value, traceback):
        if exc_type:
            print(f'An exception occurred: {exc_value}')
        return True  # Suppresses the exception

with MyContextManager() as cm:
    raise ValueError('Something went wrong!')

What happens if I return False in the exit method?

If you return False in the __exit__ method, the exception will not be suppressed and will propagate up the call stack.
