Proof: Get Iterate Parent 29

Let's prove the following theorem:

if the following are true:
  • expression state at time 29 = "iterate_args"
  • arguments stack at time 29 = [ [ locations, [ "ES", [ "Spain", [ ] ] ] ], [ ] ]
  • parent stack at time 29 = [ __setitem__(locations, "ES", "Spain"), [ ] ]

then parent stack at time 30 = [ __setitem__(locations, "ES", "Spain"), [ ] ]

Given
1 expression state at time 29 = "iterate_args"
2 arguments stack at time 29 = [ [ locations, [ "ES", [ "Spain", [ ] ] ] ], [ ] ]
3 parent stack at time 29 = [ __setitem__(locations, "ES", "Spain"), [ ] ]

# Claim Reason
1 parent stack at time (29 + 1) = parent stack at time 29 if expression state at time 29 = "iterate_args" and arguments stack at time 29 = [ [ locations, [ "ES", [ "Spain", [ ] ] ] ], [ ] ], then parent stack at time (29 + 1) = parent stack at time 29
2 parent stack at time (29 + 1) = [ __setitem__(locations, "ES", "Spain"), [ ] ] if parent stack at time (29 + 1) = parent stack at time 29 and parent stack at time 29 = [ __setitem__(locations, "ES", "Spain"), [ ] ], then parent stack at time (29 + 1) = [ __setitem__(locations, "ES", "Spain"), [ ] ]
3 29 + 1 = 30 29 + 1 = 30
4 parent stack at time (29 + 1) = parent stack at time 30 if 29 + 1 = 30, then parent stack at time (29 + 1) = parent stack at time 30
5 parent stack at time 30 = [ __setitem__(locations, "ES", "Spain"), [ ] ] if parent stack at time (29 + 1) = parent stack at time 30 and parent stack at time (29 + 1) = [ __setitem__(locations, "ES", "Spain"), [ ] ], then parent stack at time 30 = [ __setitem__(locations, "ES", "Spain"), [ ] ]
