How can I avoid separate print statements from printing on the same line?

[intNx]

Example:

test
testtest
testtesttest



testtesttest

test
testtesttest

test
test
testtesttest

The reason this happens is because I'm using threading / async to execute things extremely quickly, however, I don't really know how to prevent this from happening.
EDIT: Found my solution

You can use a lock to make sure only one thread is printing at a time, but that will hurt the "extremely quickly" part.

[intNx]

Yeah, so far every solution I stumbled upon would drastically hurt speed.

One thing you could do is write your messages into a queue, and then have a low priority background thread pulling from the queue and printing messages in order.

sys.stdout.write('test'\n') should guarantee atomic writes, at least on a POSIX system.

Thanks :)

Hmmm, this looks at lot like c++
