Lesson 3.1 · Trace it

Trace: while countdown

Python code8 rows to fill2 marks

Complete the trace table for this Python code. [2]

Line 1: n = 3
Line 2: while n > 0:
Line 3, indented 1 level: print(n)
Line 4, indented 1 level: n = n - 1
Line 5: print("go")

Fill in one row each time a line changes 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.
