## 1. What is the result of 8 % 3?

a) 2
b) 2.67
c) 3
d) 5

a) 2

### Explanation:

The % operator returns the remainder of the division. 8 divided by 3 leaves a remainder of 2.

## 2. What does the '//' operator do in Python?

a) Performs floating-point division
b) Performs floor division
c) Divides and assigns the value
d) Checks if the numbers are divisible

b) Performs floor division

### Explanation:

The '//' operator performs floor division, which divides and then rounds down to the nearest integer.

## 3. Which operator has the highest precedence in Python?

a) **
b) *
c) +
d) //

a) **

### Explanation:

The exponentiation operator (**) has the highest precedence in Python.

## 4. What is the output of 3 ** 2?

a) 6
b) 9
c) 5
d) 8

b) 9

### Explanation:

The ** operator performs exponentiation. 3 squared equals 9.

## 5. What does the 'not' operator do?

a) Negates a boolean value
b) Checks if two values are not equal
c) Reverses the order of characters
d) All of the above

a) Negates a boolean value

### Explanation:

The 'not' operator is used to negate a boolean value in Python.

## 6. What is the result of 'Python' == 'Python'?

a) True
b) False
c) Error
d) None

a) True

### Explanation:

The '==' operator checks if the values on either side are equal. Here, both strings are identical.

## 7. What is the purpose of the 'is' operator?

a) To compare values
b) To check if two variables point to the same object
c) To check if the type of two variables is the same
d) To check for equality of values and types

b) To check if two variables point to the same object

### Explanation:

The 'is' operator checks if two variables refer to the same object in memory.

## 8. What does the following expression return: not(3 > 1)?

a) True
b) False
c) Error
d) None

b) False

### Explanation:

Since 3 is greater than 1, the expression inside the parentheses is True, and the 'not' operator negates it to False.

## 9. What is the output of 'Hello' + 'World'?

a) HelloWorld
b) Hello World
c) Error
d) None

a) HelloWorld

### Explanation:

The '+' operator concatenates strings.

## 10. What is the result of 10 >> 2?

a) 2
b) 4
c) 5
d) 8

c) 5

### Explanation:

The >> operator is the right shift operator, shifting bits of 10 (1010 in binary) 2 places to the right, resulting in 5 (0101 in binary).

## 11. Which operator is used for membership testing?

a) ==
b) in
c) ::
d) is

b) in

### Explanation:

The 'in' operator is used to check if a value is a member of a sequence.

## 12. What is the output of the expression: 3 * 1 ** 3?

a) 0
b) 1
c) 3
d) 9

c) 3

### Explanation:

According to operator precedence, exponentiation is done first (1 ** 3 = 1), then multiplication (3 * 1).

## 13. How do you check if 'a' does not equal 'b' in Python?

a) a <> b
b) a != b
c) a =! b
d) not a = b

b) a != b

### Explanation:

The '!=' operator is used to check if two values are not equal.

## 14. What is the output of 2 & 3?

a) 1
b) 2
c) 3
d) 0

b) 2

### Explanation:

The & operator performs a bitwise AND operation. 2 (010 in binary) & 3 (011 in binary) results in 010, which is 2.

## 15. What does the 'or' operator do?

a) Returns True if at least one operand is true
b) Returns True if both operands are true
c) Returns the first false value
d) None of the above

a) Returns True if at least one operand is true

### Explanation:

The 'or' operator returns True if either of the operands is True.

## 16. What is the result of the expression: 'Python' and 'Programming'?

a) Python
b) Programming
c) True
d) False

b) Programming

### Explanation:

When using the 'and' operator, if both values are true, the last value is returned.

## 17. How does the += operator work?

b) Adds right operand to the left operand and assigns the result to left operand
c) Increments a variable
d) None of the above

b) Adds right operand to the left operand and assigns the result to left operand

### Explanation:

The += operator is a shorthand for performing addition and assignment in one step.

## 18. What is the output of [1, 2, 3] * 2?

a) [1, 2, 3, 1, 2, 3]
b) [2, 4, 6]
c) [1, 2, 3]
d) Error

a) [1, 2, 3, 1, 2, 3]

## 19. What is the result of 'a' < 'b'?

a) True
b) False
c) Error
d) None
