to_integral_exact(x) Rounds to an integer.

itertools.repeat(object[, times]) Make an iterator that returns object over and over again. Runs indefinitely unless the times argument is specified. Used as argument to map() for invariant parameters to the called function. Also used with zip() to create an invariant part of a tuple record. Roughly equivalent to: def repeat(object, times=None): # repeat(10, 3) --> 10 10 10 if times is None: while True: yield object else: for i in range(times):

clear() Reset the internal flag to false. Subsequently, threads calling wait() will block until set() is called to set the internal flag to true again.

_b_base_ Sometimes ctypes data instances do not own the memory block they contain, instead they share part of the memory block of a base object. The _b_base_ read-only member is the root ctypes object that owns the memory block.

socket.gethostbyname(hostname) Translate a host name to IPv4 address format. The IPv4 address is returned as a string, such as '100.50.200.5'. If the host name is an IPv4 address itself it is returned unchanged. See gethostbyname_ex() for a more complete interface. gethostbyname() does not support IPv6 name resolution, and getaddrinfo() should be used instead for IPv4/v6 dual stack support.

mapPriority(levelname) Maps a logging level name to a syslog priority name. You may need to override this if you are using custom levels, or if the default algorithm is not suitable for your needs. The default algorithm maps DEBUG, INFO, WARNING, ERROR and CRITICAL to the equivalent syslog names, and all other level names to ‘warning’.

class multiprocessing.managers.SyncManager A subclass of BaseManager which can be used for the synchronization of processes. Objects of this type are returned by multiprocessing.Manager(). It also supports creation of shared lists and dictionaries. Barrier(parties[, action[, timeout]]) Create a shared threading.Barrier object and return a proxy for it. New in version 3.3. BoundedSemaphore([value]) Create a shared threading.BoundedSemaphore object and return a proxy for it. Con

bytes.center(width[, fillbyte]) bytearray.center(width[, fillbyte]) Return a copy of the object centered in a sequence of length width. Padding is done using the specified fillbyte (default is an ASCII space). For bytes objects, the original sequence is returned if width is less than or equal to len(s). Note The bytearray version of this method does not operate in place - it always produces a new object, even if no changes were made.

recv_bytes([maxlength]) Return a complete message of byte data sent from the other end of the connection as a string. Blocks until there is something to receive. Raises EOFError if there is nothing left to receive and the other end has closed. If maxlength is specified and the message is longer than maxlength then OSError is raised and the connection will no longer be readable. Changed in version 3.3: This function used to raise IOError, which is now an alias of OSError.

close() Close the connection. This is called automatically when the connection is garbage collected.
