turtle.write_docstringdict(filename="turtle_docstringdict") Parameters: filename – a string, used as filename Create and write docstring-dictionary to a Python script with the given filename. This function has to be called explicitly (it is not used by the turtle graphics classes). The docstring dictionary will be written to the Python script filename.py. It is intended to serve as a template for translation of the docstrings into different languages.

incrementaldecoder Incremental encoder and decoder classes or factory functions. These have to provide the interface defined by the base classes IncrementalEncoder and IncrementalDecoder, respectively. Incremental codecs can maintain state.

RLock() Create a shared threading.RLock object and return a proxy for it.

POP3.top(which, howmuch) Retrieves the message header plus howmuch lines of the message after the header of message number which. Result is in form (response, ['line', ...], octets). The POP3 TOP command this method uses, unlike the RETR command, doesn’t set the message’s seen flag; unfortunately, TOP is poorly specified in the RFCs and is frequently broken in off-brand servers. Test this method by hand against the POP3 servers you will use before trusting it.

poll.modify(fd, eventmask) Modifies an already registered fd. This has the same effect as register(fd, eventmask). Attempting to modify a file descriptor that was never registered causes an OSError exception with errno ENOENT to be raised.

class pathlib.PurePath(*pathsegments) A generic class that represents the system’s path flavour (instantiating it creates either a PurePosixPath or a PureWindowsPath): >>> PurePath('setup.py') # Running on a Unix machine PurePosixPath('setup.py') Each element of pathsegments can be either a string representing a path segment, or another path object: >>> PurePath('foo', 'some/path', 'bar') PurePosixPath('foo/some/path/bar') >>> PurePath(Path('foo'), Path('bar'

array.index(x) Return the smallest i such that i is the index of the first occurrence of x in the array.

class os.terminal_size A subclass of tuple, holding (columns, lines) of the terminal window size. columns Width of the terminal window in characters. lines Height of the terminal window in characters.

class lzma.LZMADecompressor(format=FORMAT_AUTO, memlimit=None, filters=None) Create a decompressor object, which can be used to decompress data incrementally. For a more convenient way of decompressing an entire compressed stream at once, see decompress(). The format argument specifies the container format that should be used. The default is FORMAT_AUTO, which can decompress both .xz and .lzma files. Other possible values are FORMAT_XZ, FORMAT_ALONE, and FORMAT_RAW. The memlimit argument spe

time.sleep(secs) Suspend execution of the calling thread for the given number of seconds. The argument may be a floating point number to indicate a more precise sleep time. The actual suspension time may be less than that requested because any caught signal will terminate the sleep() following execution of that signal’s catching routine. Also, the suspension time may be longer than requested by an arbitrary amount because of the scheduling of other activity in the system. Changed in version
