Exceptions handle errors from "summary" of Python Programming by John M. Zelle
When writing a program, it is important to anticipate and handle errors that may occur during its execution. Errors can happen for a variety of reasons – maybe the user entered invalid input, or a file could not be found, or a network connection failed. One way to deal with errors in Python is by using exceptions. Exceptions in Python are objects that represent errors. When an error occurs in a program, an exception is raised. If the exception is not handled by the program, it will cause the program to terminate and display an error message. By using a try-except block, you can catch and handle exceptions in a more graceful way. The try block is where you place the code that might raise an exception. If an exception is raised within the try block, the program jumps to the except block.
