Question

The 'raise' keyword in Python is used ________.

• A. to throw an exception
• B. to avoid an exception
• C. to handle a keyword
• D. to find an exception

Hint:

Use try-except to handle exceptions raised by Python.
Use raise to deliberately throw an exception yourself.

Answer 1

The Correct Option is A

Concept:
In Python, exception handling allows programs to intercept, handle, and trigger errors dynamically during runtime execution.

Step 1: Role of the 'raise' Statement:
The raise keyword is used explicitly by a programmer to throw (or raise) an exception when a specific condition or business logic rule is violated.
For example:
{if age < 18: raise ValueError("Age must be at least 18")}
When the raise statement executes, the standard program flow stops immediately, and Python searches for an appropriate enclosing except block to handle the error.

Step 2: Differentiating Exception Keywords in Python:
- try: Encloses the block of code being monitored for errors.
- except: Catches and handles exceptions that occur within the try block.
- finally: Executes clean-up code unconditionally, regardless of whether an exception occurred or not.
- raise: Triggers an exception deliberately.
Final Answer:
The keyword raise is used to explicitly throw an exception.
