Python Try Except

Error handling is an important aspect of programming to ensure that your program can gracefully handle unexpected situations. In Python, you can use the try andexcept blocks to handle exceptions (errors) that occur during the execution of your code.

Basic Syntax

The basic syntax for a try-except block in Python is as follows:

try:
    # Code that might raise an exception
    result = 10 / 0
except:
    # Code to handle the exception
    print('An error occurred')

In this example, if the division by zero operation in the try block raises an exception, the except block will handle the exception and print "An error occurred".

Handling Specific Exceptions

You can also specify the type of exception to handle in the except block. For example, to handle only ZeroDivisionError exceptions:

try:
    result = 10 / 0
except ZeroDivisionError:
    print('Division by zero error')

Using the Exception Object

You can use the except block to capture the exception object and obtain more information about the exception:

try:
    result = 10 / 0
except ZeroDivisionError as e:
    print('Exception:', e)

Conclusion

The try-except block in Python allows you to gracefully handle exceptions that occur during the execution of your code. By understanding how to use try-except blocks, you can write more robust and reliable Python programs.
