Checkpoint 3: Putting it all together Now, we are going to put these together. Copy your code from the previous checkpoint to a file called check3.py. As in checkpoint 2, you will ask from the user a starting point: file number, paragraph number and the line number. You will first find the first line of the program. Then, you will construct the program using a WHILE loop, until you reach the line END/0/0/0. Write the lines you found in a file called program.py. When done, load the recovered program into Spyder and execute it. Try the following starting points: 1/5/4 4/40/2 4/42/14 Your program must report failure if your parsing fails, which would happen if you have a bug in your code for counting paragraphs and lines or an incorrect starting point is given.
