Which operator is right-associative
- A.
*
- B.
=
- C.
+
- D.
%
Correct Answer
B. =Explanation
The = operator is right-associative. This means that when there are multiple = operators in an expression, the evaluation starts from the rightmost = operator and moves towards the left. This allows for assigning a value to multiple variables in a single statement. For example, in the expression "a = b = c", the value of c is assigned to b first, and then the value of b is assigned to a.Rate this question:

What is the output of the following program? L = list('123456') L[0] = L[5] = 0 L[3] = L[-2] print(L)
- A.
[0, ‘2’, ‘3’, ‘4’, ‘5’, 0]
- B.
[‘6’, ‘2’, ‘3’, ‘5’, ‘5’, ‘6’]
- C.
[‘0’, ‘2’, ‘3’, ‘5’, ‘5’, ‘0’]
- D.
[0, ‘2’, ‘3’, ‘5’, ‘5’, 0]
Correct Answer
D. [0, ‘2’, ‘3’, ‘5’, ‘5’, 0]Explanation
The program creates a list L with elements '1', '2', '3', '4', '5', '6'. Then, it assigns the value 0 to L[0] and L[5], making the list [0, '2', '3', '4', '5', 0]. Finally, it assigns the value of L[-2] (which is '5') to L[3], resulting in the final list [0, '2', '3', '5', '5', 0].Rate this question:

Which of these is not a core data type?
- A.
List
- B.
Dictionary
- C.
Tuple
- D.
Class
Correct Answer
D. ClassExplanation
The core data types in programming languages are the fundamental building blocks for storing and manipulating data. In this question, the options provided are list, dictionary, tuple, and class. While list, dictionary, and tuple are all core data types commonly used in programming, class is not considered a core data type. A class is a blueprint for creating objects, rather than a data type itself. It is used to define the properties and behaviors of objects, making it a higher-level concept in object-oriented programming.Rate this question:

What is the Output of following program? a = 4.5 b = 2 print a//b
- A.
2
- B.
2.0
- C.
2.25
- D.
3
Correct Answer
B. 2.0Explanation
The output of the program is 2.0. The "//" operator is used for floor division, which divides the two numbers and returns the largest integer that is less than or equal to the result. In this case, 4.5 divided by 2 equals 2.25, but since floor division returns the largest integer, the output is 2.0.Rate this question:

What is the output of following program? a = True b = False c = False if not a or b: print 1 elif not a or not b and c: print 2 elif not a or b or not b and a: print 3 else: print 4
- A.
1
- B.
2
- C.
3
- D.
4
Correct Answer
C. 3Explanation
The output of the program is 3. This is because the condition in the third elif statement evaluates to True. The condition is "not a or b or not b and a", which can be simplified as "True or False or True". Since the first condition is True, the entire condition is True and the code inside the elif block is executed, which is to print 3.Rate this question:

What is the output of following program? list1 = ['physics', 'chemistry', 1997, 2000] print ("list1: ", list1[1:])
- A.
List1: ['physics', 'chemistry', 1997, 2000]
- B.
List1: ['chemistry', 1997, 2000]
- C.
['physics', 'chemistry', 1997, 2000]
- D.
['chemistry', 1997, 2000]
Correct Answer
B. List1: ['chemistry', 1997, 2000]Explanation
The program creates a list called list1 with four elements: 'physics', 'chemistry', 1997, and 2000. The print statement prints the elements of list1 starting from the index 1 (the second element) onwards. Therefore, the output is "list1: ['chemistry', 1997, 2000]".Rate this question:

- B.
(1,2,3,4)
- C.
{1,2,3,4}
- D.
{}
Correct Answer
B. (1,2,3,4)Explanation
A Python tuple is a collection of ordered, immutable elements enclosed in parentheses. In the given options, only (1,2,3,4) is enclosed in parentheses, making it a tuple. The other options are either enclosed in square brackets (making them lists) or curly braces (making them sets).Rate this question:

- A.
True
- B.
False
- C.
Error
- D.
None
Correct Answer
A. TrueExplanation
The given Python code snippet creates a dictionary named 'd' with two key-value pairs. The keys are 'john' and 'peter', and the corresponding values are 40 and 45, respectively. The code then checks if the key 'john' is present in the dictionary 'd'. Since 'john' is one of the keys in the dictionary, the output will be True.Rate this question:
