Proof: Write Stmt Class Defs At Unchanged 34

Let's prove the following theorem:

if the following are true:
  • the line at time 34 = 2
  • the tab at time 34 = 0
  • statement at line 2, tab 0 = while __lt__(a, 2):
  • Class Map at time 34 = [ ]

then Class Map at time 35 = [ ]

Given
1 the line at time 34 = 2
2 the tab at time 34 = 0
3 statement at line 2, tab 0 = while __lt__(a, 2):
4 Class Map at time 34 = [ ]
Proof Table
# Claim Reason
1 Class Map at time (34 + 1) = Class Map at time 34 if the line at time 34 = 2 and the tab at time 34 = 0 and statement at line 2, tab 0 = while __lt__(a, 2):, then Class Map at time (34 + 1) = Class Map at time 34
2 Class Map at time (34 + 1) = [ ] if Class Map at time (34 + 1) = Class Map at time 34 and Class Map at time 34 = [ ], then Class Map at time (34 + 1) = [ ]
3 34 + 1 = 35 34 + 1 = 35
4 Class Map at time (34 + 1) = Class Map at time 35 if 34 + 1 = 35, then Class Map at time (34 + 1) = Class Map at time 35
5 Class Map at time 35 = [ ] if Class Map at time (34 + 1) = Class Map at time 35 and Class Map at time (34 + 1) = [ ], then Class Map at time 35 = [ ]
