Exception

• try -> except ___Error -> except -> else (NO Errors)
• use sys.exc_info()[1] for details about an error
• to raise error(exception): use ‘raise’ keyword

import sys

try:
    # codes that might raise exceptions

    # Code below raise exception
    """
    raise TypeError('raised TypeError intenionally')
    """
except Error_Name (as e):
    print(f'caught {e}')
except:
    # other exceptions
    print(f'unkonwn error: {sys.exc_info()[1]}')
else:
    # No error raised!
