To answer this question, we need to know the definition and types of exceptions in Python.

• An exception is a Python object that represents an error. An exception may be raised even if the program is syntactically correct, meaning that it follows the rules of the Python language. However, the program may encounter an error during its execution, such as a division by zero, a file not found, or an invalid input. When an exception occurs, the normal flow of the program is interrupted and the program may terminate if the exception is not handled properly.
• There are different types of exceptions in Python, such as ZeroDivisionError , FileNotFoundError , ValueError , etc. Each type of exception has a name and a message that describes the cause of the error. For example, ZeroDivisionError is raised when we try to divide a number by zero, FileNotFoundError is raised when we try to open a file that does not exist, ValueError is raised when we try to convert a string to an integer that is not valid, etc.
• For example, consider the following program that asks the user to enter a number and prints its reciprocal:

This program is syntactically correct , but it may raise an exception depending on the user input. If the user enters a non-zero integer, such as 5, the program will work fine and print “The reciprocal of 5 is 0.2”. However, if the user enters zero, the program will raise a ZeroDivisionError and print “ZeroDivisionError: division by zero”. Similarly, if the user enters a non-integer value, such as “abc”, the program will raise a ValueError and print “ValueError: invalid literal for int() with base 10: ‘abc’”.

Therefore, the statement “An exception may be raised even if the program is syntactically correct” is true.
