Trace: nested grid

Line 1: for r in range(2):1for r in range(2):
Line 2, indented 1 level: for c in range(3):2    for c in range(3):
Line 3, indented 2 levels: print(r, c)3        print(r, c)

Fill in one row each time a line changes r or c, or prints something. The table already has the right number of rows. In each row, write only what that line changes; you can leave the other cells empty or copy their values down. Write values the way Python shows them: 3 and 3.0 are different, and text goes in quotes. In the output column, write exactly what appears on screen, with no quotes around it.
