I wouldn't put it into a class, but the core of it looks something like
this:

for line in sys.stdin:
result = process(line)
print(result)
if some_condition():
break

The details may be different, and there's likely more error handling in
production code, but that's the general idea.

Start by reading the Python tutorial
("https://docs.python.org/3/tutorial/index.html#tutorial-index;),
especially section 7.

How to design a class that will listen on stdin?

[zljubisic]

Hi,

I have to talk to outer system by stdin/stdout.
Each line that comes to stdin should be processed and its result returned back 
to stdout. Logging should go to stderr.

How to design a class that will listed to stdin and call required methods in 
order to process the data?
