Proof: Do Object Store At Unchanged 55
Let's prove the following theorem:
if the following are true:
- expression state at time 55 = "iterate_args"
- Python Object Store at time 55 = [ ]
then Python Object Store at time 56 = [ ]
Proof:
Given
1 | expression state at time 55 = "iterate_args" |
---|---|
2 | Python Object Store at time 55 = [ ] |
# | Claim | Reason |
---|---|---|
1 | Python Object Store at time (55 + 1) = Python Object Store at time 55 | if expression state at time 55 = "iterate_args", then Python Object Store at time (55 + 1) = Python Object Store at time 55 |
2 | Python Object Store at time (55 + 1) = [ ] | if Python Object Store at time (55 + 1) = Python Object Store at time 55 and Python Object Store at time 55 = [ ], then Python Object Store at time (55 + 1) = [ ] |
3 | 55 + 1 = 56 | 55 + 1 = 56 |
4 | Python Object Store at time (55 + 1) = Python Object Store at time 56 | if 55 + 1 = 56, then Python Object Store at time (55 + 1) = Python Object Store at time 56 |
5 | Python Object Store at time 56 = [ ] | if Python Object Store at time (55 + 1) = Python Object Store at time 56 and Python Object Store at time (55 + 1) = [ ], then Python Object Store at time 56 = [ ] |
