difflib.get_close_matches(word, possibilities, n=3, cutoff=0.6) Return a list of the best “good enough” matches. word is a sequence for which close matches are desired (typically a string), and possibilities is a list of sequences against which to match word (typically a list of strings). Optional argument n (default 3) is the maximum number of close matches to return; n must be greater than 0. Optional argument cutoff (default 0.6) is a float in the range [0, 1]. Possibilities that don’t sc

sorted(iterable[, key][, reverse]) Return a new sorted list from the items in iterable. Has two optional arguments which must be specified as keyword arguments. key specifies a function of one argument that is used to extract a comparison key from each list element: key=str.lower. The default value is None (compare the elements directly). reverse is a boolean value. If set to True, then the list elements are sorted as if each comparison were reversed. Use functools.cmp_to_key() to convert an

SSLContext.set_alpn_protocols(protocols) Specify which protocols the socket should advertise during the SSL/TLS handshake. It should be a list of ASCII strings, like ['http/1.1', 'spdy/2'], ordered by preference. The selection of a protocol will happen during the handshake, and will play out according to RFC 7301. After a successful handshake, the SSLSocket.selected_alpn_protocol() method will return the agreed-upon protocol. This method will raise NotImplementedError if HAS_ALPN is False.

most_common([n]) Return a list of the n most common elements and their counts from the most common to the least. If n is omitted or None, most_common() returns all elements in the counter. Elements with equal counts are ordered arbitrarily: >>> Counter('abracadabra').most_common(3) [('a', 5), ('r', 2), ('b', 2)]

exception socket.timeout A subclass of OSError, this exception is raised when a timeout occurs on a socket which has had timeouts enabled via a prior call to settimeout() (or implicitly through setdefaulttimeout()). The accompanying value is a string whose value is currently always “timed out”. Changed in version 3.3: This class was made a subclass of OSError.

class uuid.UUID(hex=None, bytes=None, bytes_le=None, fields=None, int=None, version=None) Create a UUID from either a string of 32 hexadecimal digits, a string of 16 bytes as the bytes argument, a string of 16 bytes in little-endian order as the bytes_le argument, a tuple of six integers (32-bit time_low, 16-bit time_mid, 16-bit time_hi_version, 8-bit clock_seq_hi_variant, 8-bit clock_seq_low, 48-bit node) as the fields argument, or a single 128-bit integer as the int argument. When a string

next(item) Returns the identifier of item‘s next sibling, or ‘’ if item is the last child of its parent.

bytearray.swapcase() Return a copy of the sequence with all the lowercase ASCII characters converted to their corresponding uppercase counterpart and vice-versa. For example: >>> b'Hello World'.swapcase() b'hELLO wORLD' Lowercase ASCII characters are those byte values in the sequence b'abcdefghijklmnopqrstuvwxyz'. Uppercase ASCII characters are those byte values in the sequence b'ABCDEFGHIJKLMNOPQRSTUVWXYZ'. Unlike str.swapcase(), it is always the case that bin.swapcase().swapcase(

xml.etree.ElementTree.SubElement(parent, tag, attrib={}, **extra) Subelement factory. This function creates an element instance, and appends it to an existing element. The element name, attribute names, and attribute values can be either bytestrings or Unicode strings. parent is the parent element. tag is the subelement name. attrib is an optional dictionary, containing element attributes. extra contains additional attributes, given as keyword arguments. Returns an element instance.

turtle.bye() Shut the turtlegraphics window.
