   5. u003Cclass 'int'u003E

10. Multiple Assignment Nuances

    If you write a, b = 1, 2 in Python, what are the values of a and b afterwards?

    1. a = [1, 2], b = None
    2. a = '1', b = '2'
    3. a = None, b = [1, 2]
    4. a = 1, b = 2

    5. '9'

13. Illegal Expression Use

    2. x = 1_000_000
    3. 3x = 9
    4. x = 3 // 2
    5. x, y = 1, 2

14. Input Processing and Casting

    1. A B
    2. A B C
