Proof: Write Test Call End Line22

Let's prove the following theorem:

if the following are true:
  • the line at time 22 = 3
  • the tab at time 22 = 0
  • statement at line 3, tab 0 = elif __eq__(7, 9):
  • expression state at time 22 = "end_expr"
  • Return Value at time 22 = False

then the line at time 23 = 4

Given
1 the line at time 22 = 3
2 the tab at time 22 = 0
3 statement at line 3, tab 0 = elif __eq__(7, 9):
4 expression state at time 22 = "end_expr"
5 Return Value at time 22 = False

# Claim Reason
1 the line at time (22 + 1) = 3 + 1 if the line at time 22 = 3 and the tab at time 22 = 0 and statement at line 3, tab 0 = elif __eq__(7, 9): and expression state at time 22 = "end_expr" and Return Value at time 22 = False, then the line at time (22 + 1) = 3 + 1
2 3 + 1 = 4 3 + 1 = 4
3 the line at time (22 + 1) = 4 if the line at time (22 + 1) = 3 + 1 and 3 + 1 = 4, then the line at time (22 + 1) = 4
4 22 + 1 = 23 22 + 1 = 23
5 the line at time (22 + 1) = the line at time 23 if 22 + 1 = 23, then the line at time (22 + 1) = the line at time 23
6 the line at time 23 = 4 if the line at time (22 + 1) = the line at time 23 and the line at time (22 + 1) = 4, then the line at time 23 = 4
