Test: Exception Handling in Python - 1 - CUET Humanities MCQ

Exceptions are events or conditions that occur during the execution of a program and disrupt the normal flow of the program. They are typically caused by errors in the program's logic or unexpected situations, such as dividing by zero, trying to access a non-existent file, or attempting to use a null object reference. These errors are not known until the program is running, so they are categorized as runtime errors.

The ellipsis (...) is used by the catch statement to handle all those exceptions that are not caught by other handlers.

The statement used to rethrow the exception is throw; i.e. throw without any specified exception.

The correct sequence of steps in exception handling is as follows:
B. Find the problem
D. Inform about the errors
A. Receive the error
C. Corrective actions

The function terminate() is called when exception handling fails to match with the catch statement. The function unexpected() is called, when a function throws an exception, which is not present in the throw list. Hence, by default, the function unexpected() calls the function terminate().

Wrongly written inbuilt function gives the error at compile time. All the rest are runtime errors.

The uncaught exception invokes the function terminate().

There will be multiple catch clauses with one try block. The catch block not only catches the exception but it also processes the exception.

In the real world programs, most of the exceptions are of class type, rather than any built-in data type like int, char, float, etc.

Wrong statement leads to Syntax error.

SyntaxError is raised when there is an error in the syntax of the Python code.

IOError is raised when the file specified in a program statement cannot be opened.

Import Error is raised when the requested module definition is not found.

Zero Division Error is raised when the denominator in a division operation is zero.

Name Error is raised when a local or global variable name is not defined.

A list in Python is known as a sequence data type.

Value Error is raised when a built-in method or operation receives an argument that has the right data type but mismatched or inappropriate values.

Key board Interrupt is raised when the user accidentally hits the Delete or Esc key while executing a program due to which the normal flow of the program is interrupted.

EOF Error is raised when the end of file condition is reached without reading any data by input().

Index Error is raised when the index or subscript in a sequence is out of range.
