Popen.communicate(input=None, timeout=None) Interact with process: Send data to stdin. Read data from stdout and stderr, until end-of-file is reached. Wait for process to terminate. The optional input argument should be data to be sent to the child process, or None, if no data should be sent to the child. The type of input must be bytes or, if universal_newlines was True, a string. communicate() returns a tuple (stdout_data, stderr_data). The data will be bytes or, if universal_newlines was

mapPriority(levelname) Maps a logging level name to a syslog priority name. You may need to override this if you are using custom levels, or if the default algorithm is not suitable for your needs. The default algorithm maps DEBUG, INFO, WARNING, ERROR and CRITICAL to the equivalent syslog names, and all other level names to ‘warning’.

class asyncio.StreamWriter(transport, protocol, reader, loop) Wraps a Transport. This exposes write(), writelines(), can_write_eof(), write_eof(), get_extra_info() and close(). It adds drain() which returns an optional Future on which you can wait for flow control. It also adds a transport attribute which references the Transport directly. This class is not thread safe. transport Transport. can_write_eof() Return True if the transport supports write_eof(), False if not. See WriteTra

turtle.setheading(to_angle) turtle.seth(to_angle) Parameters: to_angle – a number (integer or float) Set the orientation of the turtle to to_angle. Here are some common directions in degrees: standard mode logo mode 0 - east 0 - north 90 - north 90 - east 180 - west 180 - south 270 - south 270 - west >>> turtle.setheading(90) >>> turtle.heading() 90.0

class collections.abc.Mapping class collections.abc.MutableMapping ABCs for read-only and mutable mappings.

ipaddress.ip_network(address, strict=True) Return an IPv4Network or IPv6Network object depending on the IP address passed as argument. address is a string or integer representing the IP network. Either IPv4 or IPv6 networks may be supplied; integers less than 2**32 will be considered to be IPv4 by default. strict is passed to IPv4Network or IPv6Network constructor. A ValueError is raised if address does not represent a valid IPv4 or IPv6 address, or if the network has host bits set. >>

POP3.uidl(which=None) Return message digest (unique id) list. If which is specified, result contains the unique id for that message in the form 'response mesgnum uid, otherwise result is list (response, ['mesgnum uid', ...], octets).

xml.etree.ElementTree.fromstringlist(sequence, parser=None) Parses an XML document from a sequence of string fragments. sequence is a list or other sequence containing XML data fragments. parser is an optional parser instance. If not given, the standard XMLParser parser is used. Returns an Element instance. New in version 3.2.

IMAP4.authenticate(mechanism, authobject) Authenticate command — requires response processing. mechanism specifies which authentication mechanism is to be used - it should appear in the instance variable capabilities in the form AUTH=mechanism. authobject must be a callable object: data = authobject(response) It will be called to process server continuation responses; the response argument it is passed will be bytes. It should return bytes data that will be base64 encoded and sent to the se

parse(fp, headersonly=False) Read all the data from the binary file-like object fp, parse the resulting bytes, and return the message object. fp must support both the readline() and the read() methods on file-like objects. The bytes contained in fp must be formatted as a block of RFC 2822 style headers and header continuation lines, optionally preceded by an envelope header. The header block is terminated either by the end of the data or by a blank line. Following the header block is the bod
