b = 11
print(a | b)
print(a >> 2)

Options:

  1. 15
    10

  2. 1

  3. 14
    1

  4. 15
    1

    5. Answer:

    15
    1
    Solution:

    Bitwise right shift operator(>>): The a’s value is moved right by the 2 bits.

print(bool(0), bool(3.14159), bool(-3), bool(1.0+1j))

Options:

  1. False True True True

    • True True False True

  3. True True False True

  4. False True False True

    5. Answer:

x = 100
y = 50
print(x and y)

Options:

  1. False

  2. 50

  3. True

  4. 100

    5. Answer:
