Proof: Do Object Store At Unchanged 43

Let's prove the following theorem:

if the following are true:

expression state at time 43 = "iterate_args"
Python Object Store at time 43 = [ ]

then Python Object Store at time 44 = [ ]

Given

1	expression state at time 43 = "iterate_args"
2	Python Object Store at time 43 = [ ]

Proof Table

#	Claim	Reason
1	Python Object Store at time (43 + 1) = Python Object Store at time 43	if expression state at time 43 = "iterate_args", then Python Object Store at time (43 + 1) = Python Object Store at time 43 (Iterate Insn (6))
2	Python Object Store at time (43 + 1) = [ ]	if Python Object Store at time (43 + 1) = Python Object Store at time 43 and Python Object Store at time 43 = [ ], then Python Object Store at time (43 + 1) = [ ] (Transitive Property of Equality)
3	43 + 1 = 44	43 + 1 = 44 (Fixed Value Statement)
4	Python Object Store at time (43 + 1) = Python Object Store at time 44	if 43 + 1 = 44, then Python Object Store at time (43 + 1) = Python Object Store at time 44 (Substitution)
5	Python Object Store at time 44 = [ ]	if Python Object Store at time (43 + 1) = Python Object Store at time 44 and Python Object Store at time (43 + 1) = [ ], then Python Object Store at time 44 = [ ] (Transitive Property of Equality Variation 2)
