Exception Handling: Try, Except, and Finally Blocks
Exception handling allows your program to gracefully handle specific exceptions that may occur during its execution. This mechanism provides a mechanism to identify, process, and recover from these exceptional situations.
The syntax for using exception handling is as follows:
python
try:
except ExceptionType:
except Exception:
finally:
Let's break down the different parts of the code:
try block: This block contains the code that you want to execute normally.
except ExceptionType:: This block is executed if an exception of type ExceptionType occurs.
except Exception:: This block is executed if any kind of exception occurs.
finally block: This block is executed regardless of whether an exception occurred.
Example:
python
try:
variable = "non_existent_variable"
except ZeroDivisionError:
print("Division by zero is not allowed")
except Exception:
print("An error occurred")
finally:
print("Executing finally block even if an exception occurred")
Benefits of Exception Handling:
Protection from errors: Prevents your program from crashing or producing unexpected results.
Efficient resource management: Releases resources such as files or network connections when they are no longer needed.
Clearer error reporting: Provides detailed information about the exception, making it easier to diagnose and debug.
Key Points:
Use try block for specific exception types.
Use except block for general exceptions.
Use finally block to execute code regardless of whether an exception occurred.
Use except block for specific exception types to handle them individually
