x = None
print(x)
print(type(x))

# Always use 'is' to check for None
print(x is None)
print(x == None)  # works but 'is' is preferred

None is Python's null. Use 'is None' not '== None' because 'is' checks identity, which is both faster and safer.

Try modifying the code above to explore different behaviors. Can you extend the example to handle a new use case?
