class decimal.Decimal(value="0", context=None) Construct a new Decimal object based from value. value can be an integer, string, tuple, float, or another Decimal object. If no value is given, returns Decimal('0'). If value is a string, it should conform to the decimal numeric string syntax after leading and trailing whitespace characters are removed: sign ::= '+' | '-' digit ::= '0' | '1' | '2' | '3' | '4' | '5' | '6' | '7' | '8' | '9' indicator ::= 'e' | 'E' digit

iter_attachments() Return an iterator over all of the parts of the message that are not candidate “body” parts. That is, skip the first occurrence of each of text/plain, text/html, multipart/related, or multipart/alternative (unless they are explicitly marked as attachments via Content-Disposition: attachment), and return all remaining parts. When applied directly to a multipart/related, return an iterator over the all the related parts except the root part (ie: the part pointed to by the st

os.set_blocking(fd, blocking) Set the blocking mode of the specified file descriptor. Set the O_NONBLOCK flag if blocking is False, clear the flag otherwise. See also get_blocking() and socket.socket.setblocking(). Availability: Unix. New in version 3.5.

class logging.Formatter(fmt=None, datefmt=None, style='%') Returns a new instance of the Formatter class. The instance is initialized with a format string for the message as a whole, as well as a format string for the date/time portion of a message. If no fmt is specified, '%(message)s' is used. If no datefmt is specified, the ISO8601 date format is used. The style parameter can be one of ‘%’, ‘{‘ or ‘$’ and determines how the format string will be merged with its data: using one of %-format

user_call(frame, argument_list) This method is called from dispatch_call() when there is the possibility that a break might be necessary anywhere inside the called function.

Popen.returncode The child return code, set by poll() and wait() (and indirectly by communicate()). A None value indicates that the process hasn’t terminated yet. A negative value -N indicates that the child was terminated by signal N (POSIX only).

issuperset(other) set >= other Test whether every element in other is in the set.

sys.int_info A struct sequence that holds information about Python’s internal representation of integers. The attributes are read only. Attribute Explanation bits_per_digit number of bits held in each digit. Python integers are stored internally in base 2**int_info.bits_per_digit sizeof_digit size in bytes of the C type used to represent a digit New in version 3.1.

operator.__le__(a, b) operator.__eq__(a, b) operator.__ne__(a, b) operator.__ge__(a, b) operator.__gt__(a, b) Perform “rich comparisons” between a and b. Specifically, lt(a, b) is equivalent to a < b, le(a, b) is equivalent to a <= b, eq(a, b) is equivalent to a == b, ne(a, b) is equivalent to a != b, gt(a, b) is equivalent to a > b and ge(a, b) is equivalent to a >= b. Note that these functions can return any value, which may or may not be interpretable as a Boolean value. See Co

class asyncio.DatagramProtocol The base class for implementing datagram protocols (for use with e.g. UDP transports).
