Proof: Do Object Store At Unchanged 5

Let's prove the following theorem:

if the following are true:

expression state at time 5 = "return"
Python Object Store at time 5 = [ ]

then Python Object Store at time 6 = [ ]

Given

1	expression state at time 5 = "return"
2	Python Object Store at time 5 = [ ]

Proof Table

#	Claim	Reason
1	Python Object Store at time (5 + 1) = Python Object Store at time 5	if expression state at time 5 = "return", then Python Object Store at time (5 + 1) = Python Object Store at time 5 (Return (9))
2	Python Object Store at time (5 + 1) = [ ]	if Python Object Store at time (5 + 1) = Python Object Store at time 5 and Python Object Store at time 5 = [ ], then Python Object Store at time (5 + 1) = [ ] (Transitive Property of Equality)
3	5 + 1 = 6	5 + 1 = 6 (Fixed Value Statement)
4	Python Object Store at time (5 + 1) = Python Object Store at time 6	if 5 + 1 = 6, then Python Object Store at time (5 + 1) = Python Object Store at time 6 (Substitution)
5	Python Object Store at time 6 = [ ]	if Python Object Store at time (5 + 1) = Python Object Store at time 6 and Python Object Store at time (5 + 1) = [ ], then Python Object Store at time 6 = [ ] (Transitive Property of Equality Variation 2)
