Set Attribute Begin Parent Property

if the following are true:

  • expression state at time t = "begin_expr"
  • the expression at time t = obj.key = value

then parent stack at time (t + 1) = [ obj.key = value, parent stack at time t ]

As with any expression, when the "Expression State" is "begin_expr," LW Python pushes the "Expression" to the "Parent" stack. For example,

if the following are true:

  • expression state at time 27 = "begin_expr"
  • the expression at time 27 = self."first_name" = first_name

then parent stack at time (27 + 1) = [ self."first_name" = first_name, parent stack at time 27 ]

Try stepping through the simulator to see LW Python push "Expression" into the "Parent" stack.
