write_byte(byte) Write the integer byte into memory at the current position of the file pointer; the file position is advanced by 1. If the mmap was created with ACCESS_READ, then writing to it will raise a TypeError exception.

class importlib.abc.ResourceLoader An abstract base class for a loader which implements the optional PEP 302 protocol for loading arbitrary resources from the storage back-end. abstractmethod get_data(path) An abstract method to return the bytes for the data located at path. Loaders that have a file-like storage back-end that allows storing arbitrary data can implement this abstract method to give direct access to the data stored. OSError is to be raised if the path cannot be found. The p

SMTP.auth(mechanism, authobject, *, initial_response_ok=True) Issue an SMTP AUTH command for the specified authentication mechanism, and handle the challenge response via authobject. mechanism specifies which authentication mechanism is to be used as argument to the AUTH command; the valid values are those listed in the auth element of esmtp_features. authobject must be a callable object taking an optional single argument: data = authobject(challenge=None) If optional keyword argument ini

class logging.handlers.DatagramHandler(host, port) Returns a new instance of the DatagramHandler class intended to communicate with a remote machine whose address is given by host and port. Changed in version 3.4: If port is specified as None, a Unix domain socket is created using the value in host - otherwise, a TCP socket is created. emit() Pickles the record’s attribute dictionary and writes it to the socket in binary format. If there is an error with the socket, silently drops the p

getTestCaseNames(testCaseClass) Return a sorted sequence of method names found within testCaseClass; this should be a subclass of TestCase.

turtle.mode(mode=None) Parameters: mode – one of the strings “standard”, “logo” or “world” Set turtle mode (“standard”, “logo” or “world”) and perform reset. If mode is not given, current mode is returned. Mode “standard” is compatible with old turtle. Mode “logo” is compatible with most Logo turtle graphics. Mode “world” uses user-defined “world coordinates”. Attention: in this mode angles appear distorted if x/y unit-ratio doesn’t equal 1. Mode Initial turtle heading positive angles “st

Cmd.cmdloop(intro=None) Repeatedly issue a prompt, accept input, parse an initial prefix off the received input, and dispatch to action methods, passing them the remainder of the line as argument. The optional argument is a banner or intro string to be issued before the first prompt (this overrides the intro class attribute). If the readline module is loaded, input will automatically inherit bash-like history-list editing (e.g. Control-P scrolls back to the last command, Control-N forward to

coroutine readuntil(separator=b'n') Read data from the stream until separator is found. On success, the data and separator will be removed from the internal buffer (consumed). Returned data will include the separator at the end. Configured stream limit is used to check result. Limit sets the maximal length of data that can be returned, not counting the separator. If an EOF occurs and the complete separator is still not found, an IncompleteReadError exception will be raised, and the internal

iter(object[, sentinel]) Return an iterator object. The first argument is interpreted very differently depending on the presence of the second argument. Without a second argument, object must be a collection object which supports the iteration protocol (the __iter__() method), or it must support the sequence protocol (the __getitem__() method with integer arguments starting at 0). If it does not support either of those protocols, TypeError is raised. If the second argument, sentinel, is give

code The exit status or error message that is passed to the constructor. (Defaults to None.)
