Proof: Do Object Store At Unchanged 27

Let's prove the following theorem:

if the following are true:

expression state at time 27 = "begin_expr"
Python Object Store at time 27 = [ ]

then Python Object Store at time 28 = [ ]

Given

1	expression state at time 27 = "begin_expr"
2	Python Object Store at time 27 = [ ]

Proof Table

#	Claim	Reason
1	Python Object Store at time (27 + 1) = Python Object Store at time 27	if expression state at time 27 = "begin_expr", then Python Object Store at time (27 + 1) = Python Object Store at time 27 (Insn Count Begin Expression (6))
2	Python Object Store at time (27 + 1) = [ ]	if Python Object Store at time (27 + 1) = Python Object Store at time 27 and Python Object Store at time 27 = [ ], then Python Object Store at time (27 + 1) = [ ] (Transitive Property of Equality)
3	27 + 1 = 28	27 + 1 = 28 (Fixed Value Statement)
4	Python Object Store at time (27 + 1) = Python Object Store at time 28	if 27 + 1 = 28, then Python Object Store at time (27 + 1) = Python Object Store at time 28 (Substitution)
5	Python Object Store at time 28 = [ ]	if Python Object Store at time (27 + 1) = Python Object Store at time 28 and Python Object Store at time (27 + 1) = [ ], then Python Object Store at time 28 = [ ] (Transitive Property of Equality Variation 2)
