Question

What possible outputs(s) are expected to be displayed on screen at the time of execution of the program from the following code? Also specify the maximum values that can be assigned to each of the variables FROM and TO. 

import random

AR = [20,30,40,50,60,70]; 

FROM = random.randint(1,3) 

TO = random.randint(2,4)

for K in range(FROM,TO + 1):

print (AR[K],end=”# “)

(i)  10#40#70#

(ii)  30#40#50#

(iii)  50#60#70# 

(iv)  40#50#70#

Answer 1

Correct option is (ii) 30#40#50#

First AR is declared as a variable and has a series of different numbers.

Then, let FROM be 1 as the limit is given 1 to 3.

Then, let TO be 2 as the limit is given 2 to 4.

Now in for loop FROM is 1 and TO will become 3 as to give (FROM, TO+1).

Now FROM and TO are (1,3)

At last, as K in FROM is 1 and K in TO is 3, the number indexing on 1 to 3 will be printed with # between them.

Answer 2

(ii)  30#40#50# Maximum value FROM,TO is (3,4)
