1. What is the purpose of the "raise" keyword in Python?
Ans. The "raise" keyword in Python is used to explicitly raise an exception or error in a program. It allows the programmer to handle exceptional situations by creating custom exceptions or throwing built-in exceptions.
2. How can we raise an exception using the "raise" keyword in Python?
Ans. To raise an exception using the "raise" keyword in Python, we need to specify the type of exception to be raised, followed by an optional error message. For example, "raise ValueError('Invalid input')" will raise a ValueError exception with the specified error message.
3. Can we raise multiple exceptions in a single program using the "raise" keyword?
Ans. Yes, it is possible to raise multiple exceptions in a single program using the "raise" keyword. By placing multiple "raise" statements in different parts of the code, we can raise different exceptions based on specific conditions or situations.
