Python Help: Writing a program to read from one file line by line and number it in a new file

I'm writing this program and I found this to work for what I want. However what does the "while line:" on line 11 do. How is the "line" variable changed so that it's not an infinite loop. I know it has to do with the line=f1.readline() on line 13. But how is that line any different than the one in line 7. Also how does it know to read the next line in the inputFile?
