Proof: Do Object Store At Unchanged 28

Let's prove the following theorem:

if the following are true:

expression state at time 28 = "return"
Python Object Store at time 28 = [ ]

then Python Object Store at time 29 = [ ]

Given

1	expression state at time 28 = "return"
2	Python Object Store at time 28 = [ ]

Proof Table

#	Claim	Reason
1	Python Object Store at time (28 + 1) = Python Object Store at time 28	if expression state at time 28 = "return", then Python Object Store at time (28 + 1) = Python Object Store at time 28 (Return (9))
2	Python Object Store at time (28 + 1) = [ ]	if Python Object Store at time (28 + 1) = Python Object Store at time 28 and Python Object Store at time 28 = [ ], then Python Object Store at time (28 + 1) = [ ] (Transitive Property of Equality)
3	28 + 1 = 29	28 + 1 = 29 (Fixed Value Statement)
4	Python Object Store at time (28 + 1) = Python Object Store at time 29	if 28 + 1 = 29, then Python Object Store at time (28 + 1) = Python Object Store at time 29 (Substitution)
5	Python Object Store at time 29 = [ ]	if Python Object Store at time (28 + 1) = Python Object Store at time 29 and Python Object Store at time (28 + 1) = [ ], then Python Object Store at time 29 = [ ] (Transitive Property of Equality Variation 2)
