Exception & Error Handling in Python | Tutorial by DataCamp | DataCamp

Errors are an inevitable part of coding, but how you handle them can make a big difference in your program’s robustness. Python provides a powerful mechanism to deal with errors through exceptions. This blog will guide you on how to manage errors gracefully using try, except, and finally.

What is Exception Handling?

In Python, exceptions are errors detected during execution. Instead of letting your program crash, Python allows you to catch and handle these errors so that your program can continue running.

Basic Structure of Try-Except

The basic structure of exception handling in Python is:

Examples in Action

  1. Handling a Division by Zero:

    • This will catch the ZeroDivisionError and print a friendly message instead of crashing.
  2. Using Finally:

    The finally block will execute regardless of whether an exception occurs, making it ideal for clean-up tasks like closing files.

Best Practices

  • Use specific exceptions (ZeroDivisionError, FileNotFoundError) rather than a general Exception.

  • Always include a finally block if you need to release resources like file handles or network connections.
