  - The nested loop once more

• - The first loop iterates once

  - The nested loop iterates until it's finished

  - The first loop iterates once more

  - The nested loop repeats itself and iterates until finished

• - The first loop iterates once

  - The nested loop iterates once

  - The first loop repeats once more

  - The nested loop once once more

• - The first loop iterates until it's finished

  - The nested loop iterates until it's finished

  - Code finishes

  one 4 on row 4

• It will print:
  four 1s on row 1
  three 2s on row 2
  two 3s on row 3

Multiple Choice

What does end="" do?

• It appendeds printed items sit on the same line

• It makes all printed data types go on their own lines

• It does nothing. It's an error
