Lesson 3.4 · Trace it
Trace: sum loop
Python code9 rows to fill2 marks
Complete the trace table for this Python code. [2]
Line 1: total = 0Line 2: n = 1Line 3: while n <= 3:Line 4, indented 1 level: total = total + nLine 5, indented 1 level: n = n + 1Line 6: print(total)
Fill in one row each time a line changes total or n, 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.
