What is the difference between a list (list) and a tuple (tuple)?

What are dictionaries (dict) used for in Python?

To store key-value pairs (mapping). Example: person = {'name': 'Alice', 'age': 30} print(person['name']) # Output: Alice

What is a lambda function? When would you use it?

A lambda is an anonymous, small function, defined with the lambda keyword. f = lambda x, y: x + y print(f(2, 3)) # Output: 5

What is an exception, and how do you handle exceptions in Python?

Exceptions are runtime errors. You handle them using try and except: try: x = 1 / 0 except ZeroDivisionError: print("Division by zero!")
