Currently, I have intervals of: temp_tuple = [[-25, -14], [-21, -16], [-20, -15], [-10, -7], [-8, -5], [-6, -3], [2, 4], [2, 3], [3, 6], [12, 15], [13, 18], [14, 17], [22, 27], [25, 30], [26, 29]] in an ascending order by the lower bound. My task is to merge overlapping intervals so that the outcome comes out to be: [-25, -14] [-10, -3] [2, 6] [12, 18] [22, 30] My first attempt involved deleting intervals that are completely within previous intervals, like [-21, -16] which falls within [-25, -14]. But deleting objects within a list kept interfering with the loop condition. My second attempt at deleting unnecessary intervals was: i = 0 j = 1 while i < len(temp_tuples): while j < len(temp_tuples): if temp_tuples[1] > temp_tuples[j][1]: del temp_tuples[j] j += 1 i += 1 but this doesn't delete all the unnecessary intervals for some reason. What should I do? Continue reading...
