Can One Block of Except Statements Handle Multiple Exceptions?

Yes, in Python, one block of except statements can handle multiple exceptions. You can do this by listing multiple exception types in a single except block, separated by parentheses and commas. This approach helps in writing cleaner and simpler error-handling code when multiple exceptions need to be treated in the same way.

Let’s understand how it works with simple explanations and examples.

What Are try and except Blocks?

In Python, try and except blocks are used for exception handling.

• The try block contains code that might raise an error (exception).
• The except block catches and handles those errors, so the program doesn’t crash.

How to Handle Multiple Exceptions in One except Block

You can list multiple exceptions in one except block like this:

try:
    # code that might raise an exception
except (ExceptionType1, ExceptionType2):
    # handle both exceptions

Example:

try:
    # Some risky operations
    x = int(input("Enter a number: "))
    result = 10 / x
except (ValueError, ZeroDivisionError):
    print("You entered an invalid number or zero!")

Explanation:

• If the user enters a non-integer value, it raises a ValueError.
• If the user enters 0, it raises a ZeroDivisionError.
• The same block handles both exceptions.

Can You Have Separate except Blocks for Each Exception?

Yes! If you want to handle each exception differently, you can use multiple except blocks, one for each exception type.

Example:

try:
    x = int(input("Enter a number: "))
    result = 10 / x
except ValueError:
    print("Invalid input! Please enter a number.")
except ZeroDivisionError:
    print("Cannot divide by zero!")

Why Use a Single except Block for Multiple Exceptions?

Advantages:

• Cleaner code when the same action is taken for different exceptions.
• Simplifies handling when you don’t need to differentiate between error types.

When to Use:

• If the response to multiple exceptions is the same.
• For general error messages or logging purposes.

Conclusion

Yes, one block of except statements can handle multiple exceptions in Python.
You can group exceptions inside parentheses, and they will be handled by the same code block.
This is a common practice when you need to handle different exceptions in the same way, keeping your code simple and readable.

    # risky code
except (TypeError, ValueError, ZeroDivisionError):
    print("An error occurred!")
