Question 25

Identify the correct output(s) of the following code. Also write the minimum and the maximum possible values of the variable b.

import random
a = "Wisdom"
b = random.randint(1, 6)
for i in range(0, b, 2):
    print(a[i], end = '#')
  1. W#
  2. W#i#
  3. W#s#
  4. W#i#s#
Answer

W#, W#s#

Minimum and maximum possible values of the variable b is 1, 6.

Reason — The code imports the random module and initializes a string variable a with the value "Wisdom". It then generates a random integer b between 1 and 6, inclusive. A for loop iterates over a range from 0 to b in steps of 2, which means it only considers even indices (0, 2, 4) of the string a. In each iteration, it prints the character at the current index i of the string a, followed by a '#' character, without moving to a new line.

For possible values of b:

For b = 1:

  • Range: range(0, 1, 2) → Only includes 0
  • Step 1: i = 0 → Prints W#
  • Final Output: W#

For b = 2:

  • Range: range(0, 2, 2) → Only includes 0
  • Step 1: i = 0 → Prints W#
  • Final Output: W#

For b = 3:

  • Range: range(0, 3, 2) → Includes 0, 2
  • Step 1: i = 0 → Prints W#
  • Step 2: i = 2 → Prints s#
  • Final Output: W#s#

For b = 4:

  • Range: range(0, 4, 2) → Includes 0, 2
  • Step 1: i = 0 → Prints W#
  • Step 2: i = 2 → Prints s#
  • Final Output: W#s#

For b = 5:

  • Range: range(0, 5, 2) → Includes 0, 2, 4
  • Step 1: i = 0 → Prints W#
  • Step 2: i = 2 → Prints s#
  • Step 3: i = 4 → Prints o#
  • Final Output: W#s#o#

For b = 6:

  • Range: range(0, 6, 2) → Includes 0, 2, 4
  • Step 1: i = 0 → Prints W#
  • Step 2: i = 2 → Prints s#
  • Step 3: i = 4 → Prints o#
  • Final Output: W#s#o#
