Raising and Handling Python Exceptions

A Python program terminates as soon as it encounters an error. In Python, an error can be a syntax error or an exception.

In this course, you’ll learn what an exception is and how it differs from a syntax error. After that, you’ll learn about raising exceptions and making assertions. Then, you’ll learn how to catch exceptions to prevent your program from unintentionally ending and to change the control flow of your program:

You’ll learn about the basic use of a try … except block, as well as how to extend it using else and finally.

In this course, you’ll learn how to:

• Differentiate exceptions from syntax errors
• Use the assert keyword to check if a certain condition is met
• Write custom exceptions that subclass Exception
• Catch exceptions with a try … except block
• Use the additional keywords else and finally
• Catch built-in exceptions
