Proof: Do Object Store At Unchanged 2

Let's prove the following theorem:

if the following are true:

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

then Python Object Store at time 3 = [ ]

Given

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

Proof Table

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