`ipykernel.iostream:OutStream.init`

Signature

def __init__(self, session, pub_thread, name, pipe = None, echo = None, *, watchfd = True, isatty = False)

session : object: the session object
pub_thread : threading.Thread: the publication thread
name : str {'stderr', 'stdout'}: the name of the standard stream to replace
pipe : object: the pipe object
echo : bool: whether to echo output
watchfd : bool (default, True): Watch the file descriptor corresponding to the replaced stream. This is useful if you know some underlying code will write directly the file descriptor by its number. It will spawn a watching thread, that will swap the give file descriptor for a pipe, read from the pipe, and insert this into the current Stream.
isatty : bool (default, False): Indication of whether this stream has terminal capabilities (e.g. can handle colors)
