Lesson 6.3: Exception Handling – try, except, finally

Introduction:
Exceptions are errors that occur during program execution. Exception handling allows a program to continue running even when an error occurs, making programs more robust and user-friendly. Python uses try, except, and finally blocks for handling exceptions.

1. Basic try-except:

  • Wrap code that may cause an error in a try block.

  • Handle the error in the except block.

Example:

 
try:
num = int(input("Enter a number: "))
result = 10 / num
print(result)
except ZeroDivisionError:
print("Error: Cannot divide by zero")
except ValueError:
print("Error: Invalid input, please enter a number")

Explanation:

  • If the user enters 0, ZeroDivisionError is handled.

  • If the user enters a non-integer, ValueError is handled.

2. Using else Block:

  • Executes if no exception occurs in the try block.

 
try:
num = int(input("Enter a number: "))
except ValueError:
print("Invalid input")
else:
print(f"You entered {num} successfully")

3. Using finally Block:

  • Executes always, regardless of whether an exception occurred or not.

  • Useful for cleanup actions like closing files.

 
try:
file = open("example.txt", "r")
data = file.read()
except FileNotFoundError:
print("File not found")
finally:
print("Execution finished")
file.close() # Ensures file is closed

4. Catching Multiple Exceptions:

 
try:
num = int(input("Enter a number: "))
result = 10 / num
except (ValueError, ZeroDivisionError) as e:
print(f"An error occurred: {e}")

Practical Tips:

  • Always catch specific exceptions rather than using a general except:

  • Use finally for cleanup tasks like closing files or releasing resources

  • Use else for code that should run only if no exception occurs

Learning Outcome of This Lesson:

  • Understand what exceptions are and why they occur

  • Use try, except, else, and finally to handle errors

  • Write robust code that can handle runtime errors gracefully

  • Apply exception handling in real-world programs for better reliability
