Let’s have an example in which we will use theraisekeyword to raise an error manually. # pythontry:num=int(-23)ifnum<=0:raiseValueError("entred number is not positive")exceptValueErrorasve:print(ve) Output: The example above shows that entering the negative number raises an exception tha...
In this example, the 'divide_numbers' function checks if the denominator is zero before performing division. If it is, a 'ZeroDivisionError' is raised, preventing the division and signaling the error. The exception is then caught and handled, demonstrating how to use 'raise' for input validatio...
