title: Using ShiftRows to Rotate Values in List in Python
body: <p>I am trying to circularly shift the rows in each block in the following fashion. The first row remains the same. Shift the second row one position to the left. Shift the third row two positions to the left. Finally, shift the fourth row three positions to the left.</p>
  
  <p>How do I do this?</p>
