Initialize Expression State Property

If LW Python is in the "not_expr" state and the next statement to execute is an expression, then LW Python changes the state to "begin_expr." 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 = c
  • expression state at time t = "not_expr"
  • c is constant

then expression state at time (t + 1) = "begin_expr"

For example,

if the following are true:

  • the line at time 0 = 1
  • the tab at time 0 = 0
  • statement at line 1, tab 0 = 5
  • expression state at time 0 = "not_expr"

then expression state at time (0 + 1) = "begin_expr"

Try clicking "Next" on the simulator to see the "Expression State."
