18 Assertion(A): Tuple is a mutable data type.
Reason(R): If T = (10, 20, 30, 40), the statement T[2] = 100 will result in an error.

Section-B

19. Rewrite the code given below using for loop.
x = 8
while x >= 0:
print(x)
x = x - 2
20. Sugam has encountered some errors in the program that she had written to display the square of even numbers
and the cube of odd numbers. Rewrite the correct code after removing all syntax and logical errors:

num = input("Enter a number")
if num % 2 = 0:
print(num * num * num)
else
print(num * num )
21. What will be the output produced on the execution of following code segment?

numbers = [12,3,10,5,2,4]
length = len(numbers) - 1
while length > 0:
n1 = numbers[length]
n2 = numbers[length - 1]
if n1 % n2 != 0:
print(n1 * n2, end = '@')
else:
print(n1 + n2)
length = length - 1
