Proof: Do Object Store At Unchanged 20

Let's prove the following theorem:

if the following are true:

expression state at time 20 = "iterate_args"
Python Object Store at time 20 = [ ]

then Python Object Store at time 21 = [ ]

Given

1	expression state at time 20 = "iterate_args"
2	Python Object Store at time 20 = [ ]

Proof Table

#	Claim	Reason
1	Python Object Store at time (20 + 1) = Python Object Store at time 20	if expression state at time 20 = "iterate_args", then Python Object Store at time (20 + 1) = Python Object Store at time 20 (Iterate Insn (6))
2	Python Object Store at time (20 + 1) = [ ]	if Python Object Store at time (20 + 1) = Python Object Store at time 20 and Python Object Store at time 20 = [ ], then Python Object Store at time (20 + 1) = [ ] (Transitive Property of Equality)
3	20 + 1 = 21	20 + 1 = 21 (Fixed Value Statement)
4	Python Object Store at time (20 + 1) = Python Object Store at time 21	if 20 + 1 = 21, then Python Object Store at time (20 + 1) = Python Object Store at time 21 (Substitution)
5	Python Object Store at time 21 = [ ]	if Python Object Store at time (20 + 1) = Python Object Store at time 21 and Python Object Store at time (20 + 1) = [ ], then Python Object Store at time 21 = [ ] (Transitive Property of Equality Variation 2)
