[1] What is the output of the following Python3 program (using python 3.X version):

i = 1

while i <= 10:

i= i+1

(a): 1 3 5 7 9
(b): 2 4 6 8 10
(c): The program will go into an infinite loop, printing 1 1 1 …
(d): The program will go into an infinite loop (after possibly printing a single 1)

Answer:(d) The program will go into an infinite loop (after possibly printing a single 1)

[5] What is the output of the following program (using python 3.X version):

r,a,n = 2,10,20

term = a

for i in range(n):

term = term * r

Answer(d) 320

[6] Which of the following statements is NOT true about Python functions:

(a): A function can be called only once in a program.
(b): A function allows us to break a program into small, independent tasks.
(c): A function can call other functions.
(d): Python provides several helpful functions

Answer:(a) A function can be called only once in a program.

[7] Functions allow us to “divide and conquer” a complex programming task into simpler programming tasks.

(a): True
(b): False

Answer:(a) True

[8] Functions are the only way to write modular programs in Python.

(a): True
(b): False

Answer:(b) False

[9] Assume that the “min” function computes the minimum of two values, and “max” function computes the maximum of two values. Let x1, x2, x3 and x4 be 4 distinct integers. What can you say about the following program (using python 3.X version):

y1 = min(x1, x2)

y2 = min(x3, x4)

y3 = max(y1, y2)

(a): y3 is the largest integer among x1, x2, x3, x4.
(b): y3 is either the largest or the second largest integer among x1, x2, x3, x4.
(c): y3 is either the second largest or the third largest integer among x1, x2, x3, x4.
(d): y3 is the third largest integer among x1, x2, x3, x4.

Answer: (a) y3 is the largest integer among x1, x2, x3, x4.

[10]

Assume that the “min” function computes the minimum of two values, and “max” function computes the maximum of two values. Let x1, x2, x3 and x4 be 4 distinct integers. What can you say about the following program (using python 3.X version):

y1 = min(x1, x2)

y2 = min(x3, x4)

y3 = x1 + x2 – y1

y4 = x3 + x4 – y2

y5 = max(y3, y4)

(a): y5 is the largest integer among x1, x2, x3, x4.
(b): y5 is either the largest or the second largest integer among x1, x2, x3, x4.
(c): y5 is either the second largest or the third largest integer among x1, x2, x3, x4.
(d): Can not say anything as the data is not sufficient.

Answer:(c) y5 is either the second largest or the third largest integer among x1, x2, x3, x4.
