Elif Tab Property

If the "elif" statement tested true, then increment the tab number by 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 = elif test:
  • expression state at time t = "end_expr"
  • Return Value at time t = True

then the tab at time (t + 1) = j + 1

If the "elif" statement tested true, then begin evaluating the "elif" block by incrementing the tab (and line) by 1. For example,

if the following are true:

  • the line at time 22 = 3
  • the tab at time 22 = 0
  • statement at line 3, tab 0 = elif __eq__(3, 3):
  • expression state at time 22 = "end_expr"
  • Return Value at time 22 = True

then the tab at time (22 + 1) = 0 + 1

Try stepping through the simulator to see LW Python increment the tab number to 1.
