WriteTransport.writelines(list_of_data)
Write a list (or any iterable) of data bytes to the transport. This is functionally equivalent to calling write() on each element yielded by the iterable, but may be implemented more efficiently. | python.library.asyncio-protocol#asyncio.WriteTransport.writelines |
WriteTransport.write_eof()
Close the write end of the transport after flushing all buffered data. Data may still be received. This method can raise NotImplementedError if the transport (e.g. SSL) doesn’t support half-closed connections. | python.library.asyncio-protocol#asyncio.WriteTransport.write_eof |
asyncore — Asynchronous socket handler Source code: Lib/asyncore.py Deprecated since version 3.6: Please use asyncio instead. Note This module exists for backwards compatibility only. For new code we recommend using asyncio. This module provides the basic infrastructure for writing asynchronous socket service clien... | python.library.asyncore |
class asyncore.dispatcher
The dispatcher class is a thin wrapper around a low-level socket object. To make it more useful, it has a few methods for event-handling which are called from the asynchronous loop. Otherwise, it can be treated as a normal non-blocking socket object. The firing of low-level events at certain... | python.library.asyncore#asyncore.dispatcher |
accept()
Accept a connection. The socket must be bound to an address and listening for connections. The return value can be either None or a pair (conn, address) where conn is a new socket object usable to send and receive data on the connection, and address is the address bound to the socket on the other end of the ... | python.library.asyncore#asyncore.dispatcher.accept |
bind(address)
Bind the socket to address. The socket must not already be bound. (The format of address depends on the address family — refer to the socket documentation for more information.) To mark the socket as re-usable (setting the SO_REUSEADDR option), call the dispatcher object’s set_reuse_addr() method. | python.library.asyncore#asyncore.dispatcher.bind |
close()
Close the socket. All future operations on the socket object will fail. The remote end-point will receive no more data (after queued data is flushed). Sockets are automatically closed when they are garbage-collected. | python.library.asyncore#asyncore.dispatcher.close |
connect(address)
As with the normal socket object, address is a tuple with the first element the host to connect to, and the second the port number. | python.library.asyncore#asyncore.dispatcher.connect |
create_socket(family=socket.AF_INET, type=socket.SOCK_STREAM)
This is identical to the creation of a normal socket, and will use the same options for creation. Refer to the socket documentation for information on creating sockets. Changed in version 3.3: family and type arguments can be omitted. | python.library.asyncore#asyncore.dispatcher.create_socket |
handle_accept()
Called on listening channels (passive openers) when a connection can be established with a new remote endpoint that has issued a connect() call for the local endpoint. Deprecated in version 3.2; use handle_accepted() instead. Deprecated since version 3.2. | python.library.asyncore#asyncore.dispatcher.handle_accept |
handle_accepted(sock, addr)
Called on listening channels (passive openers) when a connection has been established with a new remote endpoint that has issued a connect() call for the local endpoint. sock is a new socket object usable to send and receive data on the connection, and addr is the address bound to the sock... | python.library.asyncore#asyncore.dispatcher.handle_accepted |
handle_close()
Called when the socket is closed. | python.library.asyncore#asyncore.dispatcher.handle_close |
handle_connect()
Called when the active opener’s socket actually makes a connection. Might send a “welcome” banner, or initiate a protocol negotiation with the remote endpoint, for example. | python.library.asyncore#asyncore.dispatcher.handle_connect |
handle_error()
Called when an exception is raised and not otherwise handled. The default version prints a condensed traceback. | python.library.asyncore#asyncore.dispatcher.handle_error |
handle_expt()
Called when there is out of band (OOB) data for a socket connection. This will almost never happen, as OOB is tenuously supported and rarely used. | python.library.asyncore#asyncore.dispatcher.handle_expt |
handle_read()
Called when the asynchronous loop detects that a read() call on the channel’s socket will succeed. | python.library.asyncore#asyncore.dispatcher.handle_read |
handle_write()
Called when the asynchronous loop detects that a writable socket can be written. Often this method will implement the necessary buffering for performance. For example: def handle_write(self):
sent = self.send(self.buffer)
self.buffer = self.buffer[sent:] | python.library.asyncore#asyncore.dispatcher.handle_write |
listen(backlog)
Listen for connections made to the socket. The backlog argument specifies the maximum number of queued connections and should be at least 1; the maximum value is system-dependent (usually 5). | python.library.asyncore#asyncore.dispatcher.listen |
readable()
Called each time around the asynchronous loop to determine whether a channel’s socket should be added to the list on which read events can occur. The default method simply returns True, indicating that by default, all channels will be interested in read events. | python.library.asyncore#asyncore.dispatcher.readable |
recv(buffer_size)
Read at most buffer_size bytes from the socket’s remote end-point. An empty bytes object implies that the channel has been closed from the other end. Note that recv() may raise BlockingIOError , even though select.select() or select.poll() has reported the socket ready for reading. | python.library.asyncore#asyncore.dispatcher.recv |
send(data)
Send data to the remote end-point of the socket. | python.library.asyncore#asyncore.dispatcher.send |
writable()
Called each time around the asynchronous loop to determine whether a channel’s socket should be added to the list on which write events can occur. The default method simply returns True, indicating that by default, all channels will be interested in write events. | python.library.asyncore#asyncore.dispatcher.writable |

class asyncore.file_dispatcher
A file_dispatcher takes a file descriptor or file object along with an optional map argument and wraps it for use with the poll() or loop() functions. If provided a file object or anything with a fileno() method, that method will be called and passed to the file_wrapper constructor. Ava... | python.library.asyncore#asyncore.file_dispatcher |
class asyncore.file_wrapper
A file_wrapper takes an integer file descriptor and calls os.dup() to duplicate the handle so that the original handle may be closed independently of the file_wrapper. This class implements sufficient methods to emulate a socket for use by the file_dispatcher class. Availability: Unix. | python.library.asyncore#asyncore.file_wrapper |
asyncore.loop([timeout[, use_poll[, map[, count]]]])
Enter a polling loop that terminates after count passes or all open channels have been closed. All arguments are optional. The count parameter defaults to None, resulting in the loop terminating only when all channels have been closed. The timeout argument sets the... | python.library.asyncore#asyncore.loop |
atexit — Exit handlers The atexit module defines functions to register and unregister cleanup functions. Functions thus registered are automatically executed upon normal interpreter termination. atexit runs these functions in the reverse order in which they were registered; if you register A, B, and C, at interpreter t... | python.library.atexit |
atexit.register(func, *args, **kwargs)
Register func as a function to be executed at termination. Any optional arguments that are to be passed to func must be passed as arguments to register(). It is possible to register the same function and arguments more than once. At normal program termination (for instance, if s... | python.library.atexit#atexit.register |
atexit.unregister(func)
Remove func from the list of functions to be run at interpreter shutdown. After calling unregister(), func is guaranteed not to be called when the interpreter shuts down, even if it was registered more than once. unregister() silently does nothing if func was not previously registered. | python.library.atexit#atexit.unregister |
exception AttributeError
Raised when an attribute reference (see Attribute references) or assignment fails. (When an object does not support attribute references or attribute assignments at all, TypeError is raised.) | python.library.exceptions#AttributeError |

Changed in version 3.4: Supp... | python.library.audioop |
audioop.add(fragment1, fragment2, width)
Return a fragment which is the addition of the two samples passed as parameters. width is the sample width in bytes, either 1, 2, 3 or 4. Both fragments should have the same length. Samples are truncated in case of overflow. | python.library.audioop#audioop.add |
audioop.adpcm2lin(adpcmfragment, width, state)
Decode an Intel/DVI ADPCM coded fragment to a linear fragment. See the description of lin2adpcm() for details on ADPCM coding. Return a tuple (sample, newstate) where the sample has the width specified in width. | python.library.audioop#audioop.adpcm2lin |
audioop.alaw2lin(fragment, width)
Convert sound fragments in a-LAW encoding to linearly encoded sound fragments. a-LAW encoding always uses 8 bits samples, so width refers only to the sample width of the output fragment here. | python.library.audioop#audioop.alaw2lin |
audioop.avg(fragment, width)
Return the average over all samples in the fragment. | python.library.audioop#audioop.avg |
audioop.avgpp(fragment, width)

audioop.findfit(fragment, reference)
Try to match reference as well as possible to a portion of fragment (which should be the longer fragment). This is (conceptually) done by taking slices out of fragment, using findfactor() to compute the best match, and minimizing the result. The fragments should both contain 2-byt... | python.library.audioop#audioop.findfit |
audioop.findmax(fragment, length)
Search fragment for a slice of length length samples (not bytes!) with maximum energy, i.e., return i for which rms(fragment[i*2:(i+length)*2]) is maximal. The fragments should both contain 2-byte samples. The routine takes time proportional to len(fragment). | python.library.audioop#audioop.findmax |
audioop.getsample(fragment, width, index)
Return the value of sample index from the fragment. | python.library.audioop#audioop.getsample |
audioop.lin2adpcm(fragment, width, state)
Convert samples to 4 bit Intel/DVI ADPCM encoding. ADPCM coding is an adaptive coding scheme, whereby each 4 bit number is the difference between one sample and the next, divided by a (varying) step. The Intel/DVI ADPCM algorithm has been selected for use by the IMA, so it ma... | python.library.audioop#audioop.lin2adpcm |
audioop.lin2alaw(fragment, width)
Convert samples in the audio fragment to a-LAW encoding and return this as a bytes object. a-LAW is an audio encoding format whereby you get a dynamic range of about 13 bits using only 8 bit samples. It is used by the Sun audio hardware, among others. | python.library.audioop#audioop.lin2alaw |
audioop.lin2lin(fragment, width, newwidth)
Convert samples between 1-, 2-, 3- and 4-byte formats. Note In some audio formats, such as .WAV files, 16, 24 and 32 bit samples are signed, but 8 bit samples are unsigned. So when converting to 8 bit wide samples for these formats, you need to also add 128 to the result: n... | python.library.audioop#audioop.lin2lin |
audioop.lin2ulaw(fragment, width)
Convert samples in the audio fragment to u-LAW encoding and return this as a bytes object. u-LAW is an audio encoding format whereby you get a dynamic range of about 14 bits using only 8 bit samples. It is used by the Sun audio hardware, among others. | python.library.audioop#audioop.lin2ulaw |
audioop.max(fragment, width)
Return the maximum of the absolute value of all samples in a fragment. | python.library.audioop#audioop.max |

audioop.ratecv(fragment, width, nchannels, inrate, outrate, state[, weightA[, weightB]])
Convert the frame rate of the input fragment. state is a tuple containing the state of the converter. The converter returns a tuple (newfragment, newstate), and newstate should be passed to the next call of ratecv(). The initial ... | python.library.audioop#audioop.ratecv |
audioop.reverse(fragment, width)
Reverse the samples in a fragment and returns the modified fragment. | python.library.audioop#audioop.reverse |
audioop.rms(fragment, width)
Return the root-mean-square of the fragment, i.e. sqrt(sum(S_i^2)/n). This is a measure of the power in an audio signal. | python.library.audioop#audioop.rms |
audioop.tomono(fragment, width, lfactor, rfactor)
Convert a stereo fragment to a mono fragment. The left channel is multiplied by lfactor and the right channel by rfactor before adding the two channels to give a mono signal. | python.library.audioop#audioop.tomono |
audioop.tostereo(fragment, width, lfactor, rfactor)
Generate a stereo fragment from a mono fragment. Each pair of samples in the stereo fragment are computed from the mono sample, whereby left channel samples are multiplied by lfactor and right channel samples by rfactor. | python.library.audioop#audioop.tostereo |
audioop.ulaw2lin(fragment, width)
Convert sound fragments in u-LAW encoding to linearly encoded sound fragments. u-LAW encoding always uses 8 bits samples, so width refers only to the sample width of the output fragment here. | python.library.audioop#audioop.ulaw2lin |
