Assertion and Reasoning Based Questions
The following questions are Assertion(A) and Reasoning(R) based questions. Mark the correct choice as
a. Both A and R are true and R is the correct explanation of A
b. Both A and R are true and R is not the correct explanation of A
c. A is true but R is false
d. A is false but R is true
Assertion(A): Every loop must have a range() in the header.
Reasoning(R): range() denotes a sequence of numbers.
Case Based Questions
1. Sumita is teaching her younger brother about dividends and divisors. To make him practice the concept, she wants to write
a program in Python that that can quickly generate all divisors of a given number. Can you help her in this task?
2. Nusrat has just studied Mersenne numbers. He knows that numbers in the form of 2n-1 are called Mersenne numbers. For
example,
2 -1 = 1, 2 -1 = 3, 2 -1 = 7, and so on.
