python | read text files and seperate to lines by character : i have text file with this example content:

12/13/18, 14:06 - her:IMG-20181213-WA0005.jpg (file attached)12/13/18, 14:06 - her:PTT-20181213-WA0006.opus (file attached)12/13/18, 14:07 - kristal: its not in the right quality?12/13/18, 14:14 - her:bla bla bla bla12/13/18, 14:43 - kristal: ok for this size12/13/18, 14:43 - kristal: somthing somthing
