If Test False Line Property

If the "if" statement test evaluated to False at time t, then the line number at time t + 1 is the current line number + 1. More formally,

if the following are true:

  • the line at time t = i
  • the tab at time t = j
  • statement at line i, tab j = if test:
  • expression state at time t = "end_expr"
  • Return Value at time t = False

then the line at time (t + 1) = i + 1

If the "if" statement test is False, then Python will skip the "if" body. The line number will be incremented by 1 (but the tab will remain the same).

For example,

if the following are true:

  • the line at time 10 = 1
  • the tab at time 11 = 0
  • statement at line 1, tab 0 = if __eq__(1, 3):
  • expression state at time 10 = "end_expr"
  • Return Value at time 11 = False

then the line at time (10 + 1) = 1 + 1

Try stepping through the simulator to see line number increment by 1.
