Exception handling is a crucial aspect of programming that allows you to manage errors and unexpected situations in your code. This tutorial will guide you through the basics of exception handling in various programming languages.

Common Exceptions

Here are some common exceptions you might encounter:

  • TypeError: Occurs when you try to perform an operation on an object of an incorrect type.
  • ValueError: Raised when a function receives an argument of an inappropriate type or value.
  • IndexError: Happens when you try to access an index that is out of range.

Handling Exceptions

To handle exceptions, you can use a try block followed by one or more except blocks. The try block contains the code that might raise an exception, and the except blocks specify the type of exception to handle and the code to execute if that exception occurs.

try:
    # Code that might raise an exception
    x = 1 / 0
except ZeroDivisionError:
    # Code to handle the exception
    print("Cannot divide by zero!")

Best Practices

  • Always use try blocks around code that might raise an exception.
  • Be specific with your except blocks to handle different types of exceptions appropriately.
  • Avoid using bare except: blocks as they can catch all exceptions, which can make debugging difficult.
