LBYL vs EAFP: Preventing or Handling Errors in Python
Dealing with errors and exceptional situations is a common requirement in programming. You can either prevent errors before they happen or handle errors after they’ve happened. In general, you’ll have two coding styles matching these strategies: look before you leap (LBYL), and easier to ask forgiveness than permission (EAFP), respectively. In this tutorial, you’ll dive into the questions and considerations surrounding LBYL vs EAFP in Python.
By learning about Python’s LBYL and EAFP coding styles, you’ll be able to decide which strategy and coding style to use when you’re dealing with errors in your code.
In this tutorial, you’ll learn how to:
- Use the LBYL and EAFP styles in your Python code
- Understand the pros and cons of LBYL
