Proof: Do Object Store At Unchanged 17

Let's prove the following theorem:

if the following are true:
  • expression state at time 17 = "iterate_args"
  • Python Object Store at time 17 = [ ]

then Python Object Store at time 18 = [ ]

Given
1 expression state at time 17 = "iterate_args"
2 Python Object Store at time 17 = [ ]
Proof Table
# Claim Reason
1 Python Object Store at time (17 + 1) = Python Object Store at time 17 if expression state at time 17 = "iterate_args", then Python Object Store at time (17 + 1) = Python Object Store at time 17
2 Python Object Store at time (17 + 1) = [ ] if Python Object Store at time (17 + 1) = Python Object Store at time 17 and Python Object Store at time 17 = [ ], then Python Object Store at time (17 + 1) = [ ]
3 17 + 1 = 18 17 + 1 = 18
4 Python Object Store at time (17 + 1) = Python Object Store at time 18 if 17 + 1 = 18, then Python Object Store at time (17 + 1) = Python Object Store at time 18
5 Python Object Store at time 18 = [ ] if Python Object Store at time (17 + 1) = Python Object Store at time 18 and Python Object Store at time (17 + 1) = [ ], then Python Object Store at time 18 = [ ]
