Proof: Do Object Store At Unchanged 51

Let's prove the following theorem:

if the following are true:

expression state at time 51 = "return"
Python Object Store at time 51 = [ ]

then Python Object Store at time 52 = [ ]

Given

1	expression state at time 51 = "return"
2	Python Object Store at time 51 = [ ]

Proof Table

#	Claim	Reason
1	Python Object Store at time (51 + 1) = Python Object Store at time 51	if expression state at time 51 = "return", then Python Object Store at time (51 + 1) = Python Object Store at time 51 (Return (9))
2	Python Object Store at time (51 + 1) = [ ]	if Python Object Store at time (51 + 1) = Python Object Store at time 51 and Python Object Store at time 51 = [ ], then Python Object Store at time (51 + 1) = [ ] (Transitive Property of Equality)
3	51 + 1 = 52	51 + 1 = 52 (Fixed Value Statement)
4	Python Object Store at time (51 + 1) = Python Object Store at time 52	if 51 + 1 = 52, then Python Object Store at time (51 + 1) = Python Object Store at time 52 (Substitution)
5	Python Object Store at time 52 = [ ]	if Python Object Store at time (51 + 1) = Python Object Store at time 52 and Python Object Store at time (51 + 1) = [ ], then Python Object Store at time 52 = [ ] (Transitive Property of Equality Variation 2)
