FAQs on Exception Handling In Python Video Lecture - Crash Course for EmSAT Achieve
| 1. What is exception handling in Python? |  |
Ans. Exception handling in Python is a mechanism that allows programmers to handle and manage errors or exceptional conditions that may occur during the execution of a program. It enables the program to gracefully handle errors and prevents the program from crashing.
| 2. What are built-in exceptions in Python? | |
Ans. Built-in exceptions in Python are predefined classes that represent different types of errors or exceptional conditions. These exceptions are part of the Python language and can be used to handle common types of errors, such as ValueError, TypeError, and FileNotFoundError, among others.
| 3. How can I define my own exception in Python? | |
Ans. To define your own exception in Python, you need to create a new class that inherits from the built-in Exception class or one of its subclasses. You can add custom attributes and methods to your exception class to provide additional information about the error. Once defined, you can raise your custom exception using the raise statement.
| 4. How does exception handling work in Python? | |
Ans. In Python, exception handling works by enclosing the code that may raise an exception in a try block. If an exception occurs within the try block, it is caught by the corresponding except block that matches the type of the exception. The except block handles the exception by executing specific code or displaying an error message. If no exception occurs, the code inside the try block is executed normally.
| 5. Why is exception handling important in Python programming? | |
Ans. Exception handling is important in Python programming because it allows for better error management and program stability. It helps in identifying and handling errors gracefully, preventing the program from crashing. Exception handling also provides the ability to recover from errors and take appropriate actions, such as logging errors, displaying user-friendly error messages, or retrying failed operations.
