Question 27(a)

What will be the output of the following code? Also, give the minimum and maximum values of the variable x.

import random
List = ["Delhi", "Mumbai", "Chennai", "Kolkata"]
for y in range(4):
    x = random.randint(1, 3)
    print(List[x], end = "#")
Answer

Minimum Value of x: 1
Maximum Value of x: 3

Output
Mumbai#Mumbai#Mumbai#Kolkata#
Explanation

The random.randint(1, 3) function generates a random integer between 1 and 3 (inclusive) in each iteration of the loop. Based on the code, the output will consist of four city names from the List:

  1. The List contains: ["Delhi", "Mumbai", "Chennai", "Kolkata"].
  2. List[x] will access the element at index x in the list.
  3. The values of x will be between 1 and 3, meaning the cities "Mumbai", "Chennai", and "Kolkata" will be printed in a random order for each iteration.
  4. Since the code uses random.randint(1, 3), the index x can never be 0, so "Delhi" (at index 0) will not be printed.
  5. The print statement uses end="#", meaning each city name will be followed by a # symbol without a newline between them.
