Proof: Do Object Store At Unchanged 16

Let's prove the following theorem:

if the following are true:

expression state at time 16 = "return"
Python Object Store at time 16 = [ ]

then Python Object Store at time 17 = [ ]

Given

1	expression state at time 16 = "return"
2	Python Object Store at time 16 = [ ]

Proof Table

#	Claim	Reason
1	Python Object Store at time (16 + 1) = Python Object Store at time 16	if expression state at time 16 = "return", then Python Object Store at time (16 + 1) = Python Object Store at time 16 (Return (9))
2	Python Object Store at time (16 + 1) = [ ]	if Python Object Store at time (16 + 1) = Python Object Store at time 16 and Python Object Store at time 16 = [ ], then Python Object Store at time (16 + 1) = [ ] (Transitive Property of Equality)
3	16 + 1 = 17	16 + 1 = 17 (Fixed Value Statement)
4	Python Object Store at time (16 + 1) = Python Object Store at time 17	if 16 + 1 = 17, then Python Object Store at time (16 + 1) = Python Object Store at time 17 (Substitution)
5	Python Object Store at time 17 = [ ]	if Python Object Store at time (16 + 1) = Python Object Store at time 17 and Python Object Store at time (16 + 1) = [ ], then Python Object Store at time 17 = [ ] (Transitive Property of Equality Variation 2)
