Filter output / print one record per event or time period
I've got a custom HID device which prints out exact coordinates of touched points at real time.
It is very sensitive & currently printing out the coordinate that's being touched on multiple numbers. But I need them to be printed one event at a time.
The crucial point is that I need the events to be printed without gap.(none of the events could be omitted to be printed) and of course no delay is allowed.
Current Form:
A1
A1
A1
A2
A2
C3

D1

What I expect is:
A1

D1
python printf filter real-time events

Please check that Olorin's edit is correct. Of course it is better to show the output in code blocks, but the edit also changed the output fromA1 A1 A1 A2
... in one long line toA1
A1
A1
A2
... in separate lines.

@Bodo if you inspect the source of the original revision, it was one per line originally, but Markdown doesn't show it that way.

Ifuniq
is working in a form of printing one from each type, then it won't work for my case. I need to just get the repetitive distinct touches as well. For example two different A1s can come one after. Or I need an exception handling mechanism in order not to send some wrong characters inside. So any ideas?
