class email.mime.text.MIMEText(_text, _subtype='plain', _charset=None) Module: email.mime.text A subclass of MIMENonMultipart, the MIMEText class is used to create MIME objects of major type text. _text is the string for the payload. _subtype is the minor type and defaults to plain. _charset is the character set of the text and is passed as an argument to the MIMENonMultipart constructor; it defaults to us-ascii if the string contains only ascii code points, and utf-8 otherwise. The _charset

match.start([group]) match.end([group]) Return the indices of the start and end of the substring matched by group; group defaults to zero (meaning the whole matched substring). Return -1 if group exists but did not contribute to the match. For a match object m, and a group g that did contribute to the match, the substring matched by group g (equivalent to m.group(g)) is m.string[m.start(g):m.end(g)] Note that m.start(group) will equal m.end(group) if group matched a null string. For example,

shlex.error_leader(infile=None, lineno=None) This method generates an error message leader in the format of a Unix C compiler error label; the format is '"%s", line %d: ', where the %s is replaced with the name of the current source file and the %d with the current input line number (the optional arguments can be used to override these). This convenience is provided to encourage shlex users to generate error messages in the standard, parseable format understood by Emacs and other Unix tools.

@functools.singledispatch(default) Transforms a function into a single-dispatch generic function. To define a generic function, decorate it with the @singledispatch decorator. Note that the dispatch happens on the type of the first argument, create your function accordingly: >>> from functools import singledispatch >>> @singledispatch ... def fun(arg, verbose=False): ... if verbose: ... print("Let me just say,", end=" ") ... print(arg) To add overloaded imp

socket.settimeout(value) Set a timeout on blocking socket operations. The value argument can be a nonnegative floating point number expressing seconds, or None. If a non-zero value is given, subsequent socket operations will raise a timeout exception if the timeout period value has elapsed before the operation has completed. If zero is given, the socket is put in non-blocking mode. If None is given, the socket is put in blocking mode. For further information, please consult the notes on sock

ssl.create_default_context(purpose=Purpose.SERVER_AUTH, cafile=None, capath=None, cadata=None) Return a new SSLContext object with default settings for the given purpose. The settings are chosen by the ssl module, and usually represent a higher security level than when calling the SSLContext constructor directly. cafile, capath, cadata represent optional CA certificates to trust for certificate verification, as in SSLContext.load_verify_locations(). If all three are None, this function can c

strerror The corresponding error message, as provided by the operating system. It is formatted by the C functions perror() under POSIX, and FormatMessage() under Windows.

class email.headerregistry.AddressHeader Address headers are one of the most complex structured header types. The AddressHeader class provides a generic interface to any address header. This header type provides the following additional attributes: groups A tuple of Group objects encoding the addresses and groups found in the header value. Addresses that are not part of a group are represented in this list as single-address Groups whose display_name is None. addresses A tuple of Add

gzip.compress(data, compresslevel=9) Compress the data, returning a bytes object containing the compressed data. compresslevel has the same meaning as in the GzipFile constructor above. New in version 3.2.

class time.struct_time The type of the time value sequence returned by gmtime(), localtime(), and strptime(). It is an object with a named tuple interface: values can be accessed by index and by attribute name. The following values are present: Index Attribute Values 0 tm_year (for example, 1993) 1 tm_mon range [1, 12] 2 tm_mday range [1, 31] 3 tm_hour range [0, 23] 4 tm_min range [0, 59] 5 tm_sec range [0, 61]; see (2) in strftime() description 6 tm_wday range [0, 6], Monday is 0 7 tm_yday
