How do I use try and except in Python?

How do I use try and except in Python?

In Python, you can use try and except blocks to handle exceptions. Here's a basic example:

try:
    # Code that may raise an exception
    result = 10 / 0
except ZeroDivisionError:
    print('You cannot divide by zero!')

What happens if I don't use try and except?

If you don't use try and except, your program will crash when it encounters an error, and you'll see a traceback.

Can I catch multiple exceptions?

Yes, you can catch multiple exceptions by specifying them in a tuple:

try:
    # Code that may raise an exception
    result = int('string')
except (ValueError, ZeroDivisionError) as e:
    print(f'An error occurred: {e}')

Is there a way to execute code after the try-except block?

Yes, you can use the finally block to execute code after the try-except, regardless of whether an exception occurred.
