What are augmented assignment operators? How are they useful?

Given three Boolean variables a, b, c as : a = False, b = True, c = False. Evaluate the following Boolean expressions:

(a) b and c

(b) b or c

(c) not a and b

(d) (a and b) or not c

(e) not b and not (a or c)

(f) not ((not b or not a) and c) or a

What will the result given by the following?

(a) type (6 + 3)

(b) type (6 -3)

(c) type (6 *3)

(d) type (6 / 3)

(e) type (6 // 3)

(f) type (6 % 3)

What would following code fragments result in? Given x = 3.

(a) 1 < x

(b) x >= 4

(c) x == 3

(d) x == 3.0

(e) "Hello" == "Hello"

(f) "Hello" > "hello"

(g) 4/2 == 2.0

(h) 4/2 == 2

(i) x < 7 and 4 > 5.
