Python - break statement not working in else statement within while loop

Question

The while loop in my code refuses to terminate when I use the break statement, and I'm really confused why this is happening.

point = 0
while point < len(list_of_line_lists) - 1:
    sentence = list_of_line_lists[point]["text"]
    datapoint = point
    while True:
        try:
            if list_of_line_lists[datapoint]["author"] == list_of_line_lists[datapoint + 1]["author"]:
                sentence += list_of_line_lists[datapoint + 1]["text"]
                datapoint += 1
                print(datapoint)
            else:
                print("this isn't breaking")
                break
        except IndexError:
            break

In my code above, the break statement within the else statement refuses to trigger. The code within it is executed, as there's a flurry of "this isn't breaking" in the output, but the loop itself doesn't terminate. This is how my output looks(until I manually stop it myself):

this isn't breaking
this isn't breaking
this isn't breaking
this isn't breaking
this isn't breaking
this isn't breaking
this isn't breaking

Any ideas to why this is happening?

Answer 1

The inner loop is breaking, but the outer loop isn't. The reason is because you are using the point variable in the outer while loop, but that (point) variable value is never changed (incremented/decremented).
