📘 What is the finally block?
The finally block always executes whether an exception occurs or not.
It's commonly used to close files, release resources, or perform clean-up actions.
try:
x = 5 / 0
except ZeroDivisionError:
print("Cannot divide by zero.")
finally:
print("This block always executes.")
📘 What is the else block?
The else block executes only if no exception occurs in the try block.
try:
num = int(input("Enter a number: "))
print("You entered:", num)
except ValueError:
print("That's not a number!")
else:
print("No error occurred.")

📍 Real-Time Example: Imagine you're trying to withdraw cash from an ATM:
try: Insert card and enter PIN.
except: If wrong PIN – show error.
else: If correct PIN – dispense cash.
finally: Return the card (always happens).
