How can I use try-except blocks effectively in Python?

How can I use try-except blocks effectively in Python?

You can use try-except blocks to handle exceptions gracefully. Would you like to see some advanced examples?

Yes, please provide an example of nested try-except.

Sure! Here's an example:

try:
    x = int(input('Enter a number: '))
    try:
        result = 10 / x
    except ZeroDivisionError:
        print('You cannot divide by zero!')
    else:
        print('Result:', result)
except ValueError:
    print('Invalid input! Please enter a number.')

What about using finally and else with try-except?

The else block runs if no exceptions occur, while finally runs regardless. Here's an example:

try:
    x = int(input('Enter a number: '))
except ValueError:
    print('Invalid input!')
else:
    print('You entered:', x)
finally:
    print('Execution complete.')
