curses.keyname(k) Return the name of the key numbered k. The name of a key generating printable ASCII character is the key’s character. The name of a control-key combination is a two-character string consisting of a caret followed by the corresponding printable ASCII character. The name of an alt-key combination (128-255) is a string consisting of the prefix ‘M-‘ followed by the name of the corresponding ASCII character.

ossaudiodev.open(mode) ossaudiodev.open(device, mode) Open an audio device and return an OSS audio device object. This object supports many file-like methods, such as read(), write(), and fileno() (although there are subtle differences between conventional Unix read/write semantics and those of OSS audio devices). It also supports a number of audio-specific methods; see below for the complete list of methods. device is the audio device filename to use. If it is not specified, this module firs

xml.etree.ElementTree.tostringlist(element, encoding="us-ascii", method="xml", *, short_empty_elements=True) Generates a string representation of an XML element, including all subelements. element is an Element instance. encoding [1] is the output encoding (default is US-ASCII). Use encoding="unicode" to generate a Unicode string (otherwise, a bytestring is generated). method is either "xml", "html" or "text" (default is "xml"). short_empty_elements has the same meaning as in ElementTree.wri

find(match, namespaces=None) Finds the first subelement matching match. match may be a tag name or a path. Returns an element instance or None. namespaces is an optional mapping from namespace prefix to full name.

resource.getrusage(who) This function returns an object that describes the resources consumed by either the current process or its children, as specified by the who parameter. The who parameter should be specified using one of the RUSAGE_* constants described below. The fields of the return value each describe how a particular system resource has been used, e.g. amount of time spent running is user mode or number of times the process was swapped out of main memory. Some values are dependent

pkgutil.find_loader(fullname) Retrieve a PEP 302 module loader for the given fullname. This is a backwards compatibility wrapper around importlib.util.find_spec() that converts most failures to ImportError and only returns the loader rather than the full ModuleSpec. Changed in version 3.3: Updated to be based directly on importlib rather than relying on the package internal PEP 302 import emulation. Changed in version 3.4: Updated to be based on PEP 451

assertRaisesRegex(exception, regex, callable, *args, **kwds) assertRaisesRegex(exception, regex, msg=None) Like assertRaises() but also tests that regex matches on the string representation of the raised exception. regex may be a regular expression object or a string containing a regular expression suitable for use by re.search(). Examples: self.assertRaisesRegex(ValueError, "invalid literal for.*XYZ'$", int, 'XYZ') or: with self.assertRaisesRegex(ValueError, 'literal'

statistics.mean(data) Return the sample arithmetic mean of data, a sequence or iterator of real-valued numbers. The arithmetic mean is the sum of the data divided by the number of data points. It is commonly called “the average”, although it is only one of many different mathematical averages. It is a measure of the central location of the data. If data is empty, StatisticsError will be raised. Some examples of use: >>> mean([1, 2, 3, 4, 4]) 2.8 >>> mean([-1.0, 2.5, 3.25, 5

class importlib.abc.PathEntryFinder An abstract base class representing a path entry finder. Though it bears some similarities to MetaPathFinder, PathEntryFinder is meant for use only within the path-based import subsystem provided by PathFinder. This ABC is a subclass of Finder for compatibility reasons only. New in version 3.3. find_spec(fullname, target=None) An abstract method for finding a spec for the specified module. The finder will search for the module only within the path ent

Telnet.mt_interact() Multithreaded version of interact().
