Error Handling in Python

2. Exception Usage

bookDetect and Catch

Now, let's start to learn the error handling structure.

To handle an error, you need to follow the following steps:

  1. Select the code block for detection using the try keyword.
  2. Catch an error using the except keyword.

Keywords

The try keyword defines the code block that executes inside the global scope of your program and the except keyword catch and error:

123456789101112131415
a = 15 b = 5 c = 10 try: a = a // 5 b = b // 0 c = c // 2 except: print("An error was caught.") print("a =", a) print("b =", b) print("c =", c)
copy

In a few words, the Python interpreter expects an error inside the try code block. If an error is raised, the interpreter executes the except code block.
