Proof: Get Iterate Parent 44
Let's prove the following theorem:
if the following are true:
- expression state at time 44 = "iterate_args"
- arguments stack at time 44 = [ [
__add__(self.x, 5)
, [ ] ], [ ] ] - parent stack at time 44 = [ self."x" =
__add__(self.x, 5)
, [ ] ]
then parent stack at time 45 = [ self."x" = __add__(self.x, 5)
, [ ] ]
Proof:
Given
1 | expression state at time 44 = "iterate_args" |
---|---|
2 | arguments stack at time 44 = [ [ __add__(self.x, 5) , [ ] ], [ ] ] |
3 | parent stack at time 44 = [ self."x" = __add__(self.x, 5) , [ ] ] |
# | Claim | Reason |
---|---|---|
1 | parent stack at time (44 + 1) = parent stack at time 44 | if expression state at time 44 = "iterate_args" and arguments stack at time 44 = [ [ __add__(self.x, 5) , [ ] ], [ ] ], then parent stack at time (44 + 1) = parent stack at time 44 |
2 | parent stack at time (44 + 1) = [ self."x" = __add__(self.x, 5) , [ ] ] |
if parent stack at time (44 + 1) = parent stack at time 44 and parent stack at time 44 = [ self."x" = __add__(self.x, 5) , [ ] ], then parent stack at time (44 + 1) = [ self."x" = __add__(self.x, 5) , [ ] ] |
3 | 44 + 1 = 45 | 44 + 1 = 45 |
4 | parent stack at time (44 + 1) = parent stack at time 45 | if 44 + 1 = 45, then parent stack at time (44 + 1) = parent stack at time 45 |
5 | parent stack at time 45 = [ self."x" = __add__(self.x, 5) , [ ] ] |
if parent stack at time (44 + 1) = parent stack at time 45 and parent stack at time (44 + 1) = [ self."x" = __add__(self.x, 5) , [ ] ], then parent stack at time 45 = [ self."x" = __add__(self.x, 5) , [ ] ] |
