peek([size]) Return bytes from the stream without advancing the position. At most one single read on the raw stream is done to satisfy the call. The number of bytes returned may be less or more than requested.

errors A list of the non-fatal errors encountered while loading tests. Not reset by the loader at any point. Fatal errors are signalled by the relevant a method raising an exception to the caller. Non-fatal errors are also indicated by a synthetic test that will raise the original error when run. New in version 3.5.

os.path.isfile(path) Return True if path is an existing regular file. This follows symbolic links, so both islink() and isfile() can be true for the same path.

os.getpriority(which, who) Get program scheduling priority. The value which is one of PRIO_PROCESS, PRIO_PGRP, or PRIO_USER, and who is interpreted relative to which (a process identifier for PRIO_PROCESS, process group identifier for PRIO_PGRP, and a user ID for PRIO_USER). A zero value for who denotes (respectively) the calling process, the process group of the calling process, or the real user ID of the calling process. Availability: Unix. New in version 3.3.

Logger.error(msg, *args, **kwargs) Logs a message with level ERROR on this logger. The arguments are interpreted as for debug().

Wave_read.readframes(n) Reads and returns at most n frames of audio, as a string of bytes.

handle_close() Called when the socket is closed.

operator.__add__(a, b) Return a + b, for a and b numbers.

getvalue() Return a str containing the entire contents of the buffer. Newlines are decoded as if by read(), although the stream position is not changed.
