Correct answer is : D

It outputs -5.551115123125783e-17
0.1, 0.2 and 0.3 can be represented accurately in binary

Correct answer is : B

~xis equivalent to -(x+1)
print(~7) is equivalent to print(-(7+1)) i.e.- 8
print(~~7) is equivalent to print(-(-8+1)) i.e 7
print(~~~7) is equivalent to print(-(7+1)) i.e -8

Correct answer is : A

In python the numbers starting with 0 are octal and octal number 9 not allowed in octal number

Correct answer is : A

"%" has higher precedence than "-"
So 24 % 56 will be evaluated first.

Correct answer is : A

Here the operator precedences is in this order: // -> % -> +
So 44 // 7 + 7 % 3will be evaluated as(44 // 7) + (7 % 3)

Correct answer is : C

(8+7.0)get evaluated then 18.00 / 15.0 becomes 1.2 .
Parentheses has higher precedence than "/"

Correct answer is : B

Correct answer is : A

"-" has higher precedence than "<<" . So this expression (6 << (3 - 2)) will be evaluated as (6 << 1) which results in 12

Correct answer is : C

inand not in are a membership operator.

2 in [3, 5, 6] # False
2 not in [3, 5, 6] # True

Correct answer is : B

With this expression x = y = z we are assigning a single value to multiple variables x, y and z
So 10, 20, "amazon" becomes a single value for x, y and z.
The expression without parentheses becomes a tuple.
Therefore the result will be

(10, 20, 'amazon') (10, 20, 'amazon') (10, 20, 'amazon')
