Begin Expression State Property

If LW Python is in the "begin_expr" state and "Expression" is a function call, then the next state is "iterate_args."

if the following are true:

  • expression state at time t = "begin_expr"
  • the expression at time t = function call with name: name and arguments: args

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

Try verifying this rule on the simulator:

Examples

if the following are true:

  • expression state at time 2 = "begin_expr"
  • the expression at time 2 = function call with name: __add__ and arguments: [ 5, [ 2, [ ] ] ]

then expression state at time (2 + 1) = "iterate_args"


if the following are true:

  • expression state at time 6 = "begin_expr"
  • the expression at time 6 = function call with name: fly and arguments: [ airplane, [ ] ]

then expression state at time (6 + 1) = "iterate_args"
