pexpect equivalent of Expect's “send_user”

Question

As a continuation from my previous question on building interactive option menus in pexpect, print statements within an interact input filter do not get sent to stdout until aft

Answer 1

Don't really know why print()'ed data is not automatically flushed when interacting with the spawned child but you can flush it explicitly so it would show up realtime:

print('something')
sys.stdout.flush()

or just use (only for python3)

# .raw is not buffered
sys.stdout.buffer.raw.write('something')
