Question

One of the following 10 statements generates an error. Which one? (Your answer should be a number between 1 and 10.) x = ["sun",[17],2,"king",[3,4]] # Statement 1 y = x[0:8] # Statement 2 z = x # Statement 3 w = y # Statement 4 z[0] = 0 # Statement 5 y[0] = y[0][0:3] + 'k' # Statement 6 y[1][1:3] = [5,8] # Statement 7 x[0] = x[0][1:3] # Statement 8 w[4][0] = 1000 # Statement 9 a = (x[4][1] == 4) # Statement 10

Answer 2

Answer:

Statement 8 generates an error.

Explanation:

• The following list has been allocated to 'x':

                  x = ["sun", [17], 2, "king", [3, 4]]

• We also have the following assertions:

x = ["sun",[17],2,"king",[3,4]] # Statement 1

y = x[0:8]                              # Statement 2

z = x                                    # Statement 3

w = y                                   # Statement 4

z[0] = 0                               # Statement 5

y[0] = y[0][0:3] + 'k'            # Statement 6

y[1][1:3] = [5,8]                    # Statement 7

x[0] = x[0][1:3]                     # Statement 8

w[4][0] = 1000                   # Statement 9

a = (x[4][1] == 4)                  # Statement 10

Statement #7, which reads as follows, generates an error:

• x[0] = x[0][1:3]

Reason:

• Because after running all of those statements [until #6], the entry at position 0 in the list becomes '0', it generates an error. In #7, we're attempting to traverse the element's characters, despite the fact that 0 is an int value that cannot be traversed.
