# Tutorial: Handling exceptions in python

# ------------------------------------------------------------------------------------

# You can handle exceptions in a try / except blocks
# The program executes the code in the try block,
# if something goes wrong an exception is raised
# It will be handled by the except block,
# if not the except section will be ignored.


try:
    a = 2
    a = a - 1
    print("Working!!")
    if a == 0:
        # Here a custom exception is raised if a is equal to 0
        raise ValueError("a cannot be 0")
except ValueError:
    print('Something went wrong')
    raise

# Challenge: Create a try / except block and raise a custom exception when the value received is not a number
