Proof: Do Object Store At Unchanged 38

Let's prove the following theorem:

if the following are true:

expression state at time 38 = "begin_expr"
Python Object Store at time 38 = [ ]

then Python Object Store at time 39 = [ ]

Given

1	expression state at time 38 = "begin_expr"
2	Python Object Store at time 38 = [ ]

Proof Table

#	Claim	Reason
1	Python Object Store at time (38 + 1) = Python Object Store at time 38	if expression state at time 38 = "begin_expr", then Python Object Store at time (38 + 1) = Python Object Store at time 38 (Insn Count Begin Expression (6))
2	Python Object Store at time (38 + 1) = [ ]	if Python Object Store at time (38 + 1) = Python Object Store at time 38 and Python Object Store at time 38 = [ ], then Python Object Store at time (38 + 1) = [ ] (Transitive Property of Equality)
3	38 + 1 = 39	38 + 1 = 39 (Fixed Value Statement)
4	Python Object Store at time (38 + 1) = Python Object Store at time 39	if 38 + 1 = 39, then Python Object Store at time (38 + 1) = Python Object Store at time 39 (Substitution)
5	Python Object Store at time 39 = [ ]	if Python Object Store at time (38 + 1) = Python Object Store at time 39 and Python Object Store at time (38 + 1) = [ ], then Python Object Store at time 39 = [ ] (Transitive Property of Equality Variation 2)
