Python Code Analysis

The Python code provided aims to print a pattern. Let's break down the code's execution:

  • The first `print('--x--')` statement executes once, printing the string '--x--'.
  • The `for k in range(2):` loop will iterate twice (for k=0 and k=1).
  • Inside the loop:
    • `print('-x-x-')` prints the string '-x-x-'.
    • `print('x---x')` prints the string 'x---x'.
    • `print('-x-x-')` prints the string '-x-x-'.
    • `print('--x--')` prints the string '--x--'.

Therefore, the output will be:

--x--
-x-x-
x---x
-x-x-
--x--
-x-x-
x---x
-x-x-
--x--

Options Analysis

Now, let's compare this expected output with the provided options:

  • Option 1:
  • --x--
    -x-x-
    X---X
    -x-x-
    X---X
    -x-x-
    --x--

    This option does not match the full output, as the loop's content is repeated only once in the output.

  • Option 2:
  • --x--
    -x-x-
    X---X
    -x-x-
    --x--
    X---X
    -x-x-
    --x--

    This option also does not match the full output.

  • Option 3:
  • --x--
    -x-x-
    X---X
    -x-x-
    --x--
    -x-x-
    X---X
    -x-x-
    --x--

    This option correctly represents the output of the Python code.

Final Answer Selection: Based on the step-by-step execution of the Python code, Option 3 is the correct representation of the output.
