Proof: Do Object Store At Unchanged 52
Let's prove the following theorem:
if the following are true:
- expression state at time 52 = "iterate_args"
- Python Object Store at time 52 = [ ]
then Python Object Store at time 53 = [ ]
Proof:
Given
1 | expression state at time 52 = "iterate_args" |
---|---|
2 | Python Object Store at time 52 = [ ] |
# | Claim | Reason |
---|---|---|
1 | Python Object Store at time (52 + 1) = Python Object Store at time 52 | if expression state at time 52 = "iterate_args", then Python Object Store at time (52 + 1) = Python Object Store at time 52 |
2 | Python Object Store at time (52 + 1) = [ ] | if Python Object Store at time (52 + 1) = Python Object Store at time 52 and Python Object Store at time 52 = [ ], then Python Object Store at time (52 + 1) = [ ] |
3 | 52 + 1 = 53 | 52 + 1 = 53 |
4 | Python Object Store at time (52 + 1) = Python Object Store at time 53 | if 52 + 1 = 53, then Python Object Store at time (52 + 1) = Python Object Store at time 53 |
5 | Python Object Store at time 53 = [ ] | if Python Object Store at time (52 + 1) = Python Object Store at time 53 and Python Object Store at time (52 + 1) = [ ], then Python Object Store at time 53 = [ ] |
