Proof: Do Object Store At Unchanged 31

Let's prove the following theorem:

if the following are true:
  • expression state at time 31 = "return"
  • Python Object Store at time 31 = [ ]

then Python Object Store at time 32 = [ ]

Given
1 expression state at time 31 = "return"
2 Python Object Store at time 31 = [ ]
Proof Table
# Claim Reason
1 Python Object Store at time (31 + 1) = Python Object Store at time 31 if expression state at time 31 = "return", then Python Object Store at time (31 + 1) = Python Object Store at time 31
2 Python Object Store at time (31 + 1) = [ ] if Python Object Store at time (31 + 1) = Python Object Store at time 31 and Python Object Store at time 31 = [ ], then Python Object Store at time (31 + 1) = [ ]
3 31 + 1 = 32 31 + 1 = 32
4 Python Object Store at time (31 + 1) = Python Object Store at time 32 if 31 + 1 = 32, then Python Object Store at time (31 + 1) = Python Object Store at time 32
5 Python Object Store at time 32 = [ ] if Python Object Store at time (31 + 1) = Python Object Store at time 32 and Python Object Store at time (31 + 1) = [ ], then Python Object Store at time 32 = [ ]
