fetchmany(size=cursor.arraysize) Fetches the next set of rows of a query result, returning a list. An empty list is returned when no more rows are available. The number of rows to fetch per call is specified by the size parameter. If it is not given, the cursor’s arraysize determines the number of rows to be fetched. The method should try to fetch as many rows as indicated by the size parameter. If this is not possible due to the specified number of rows not being available, fewer rows may b

class sqlite3.Row A Row instance serves as a highly optimized row_factory for Connection objects. It tries to mimic a tuple in most of its features. It supports mapping access by column name and index, iteration, representation, equality testing and len(). If two Row objects have exactly the same columns and their members are equal, they compare equal. keys() This method returns a list of column names. Immediately after a query, it is the first member of each tuple in Cursor.description.

xml.etree.ElementTree.tostring(element, encoding="us-ascii", method="xml", *, short_empty_elements=True) Generates a string representation of an XML element, including all subelements. element is an Element instance. encoding [1] is the output encoding (default is US-ASCII). Use encoding="unicode" to generate a Unicode string (otherwise, a bytestring is generated). method is either "xml", "html" or "text" (default is "xml"). short_empty_elements has the same meaning as in ElementTree.write()

Decompress.flush([length]) All pending input is processed, and a bytes object containing the remaining uncompressed output is returned. After calling flush(), the decompress() method cannot be called again; the only realistic action is to delete the object. The optional parameter length sets the initial size of the output buffer.

os.stat_float_times([newvalue]) Determine whether stat_result represents time stamps as float objects. If newvalue is True, future calls to stat() return floats, if it is False, future calls return ints. If newvalue is omitted, return the current setting. For compatibility with older Python versions, accessing stat_result as a tuple always returns integers. Python now returns float values by default. Applications which do not work correctly with floating point time stamps can use this functi

add_done_callback(fn) Add a callback to be run when the future becomes done. The callback is called with a single argument - the future object. If the future is already done when this is called, the callback is scheduled with call_soon(). Use functools.partial to pass parameters to the callback. For example, fut.add_done_callback(functools.partial(print, "Future:", flush=True)) will call print("Future:", fut, flush=True).

class xmlrpc.client.Binary This class may be initialized from bytes data (which may include NULs). The primary access to the content of a Binary object is provided by an attribute: data The binary data encapsulated by the Binary instance. The data is provided as a bytes object. Binary objects have the following methods, supported mainly for internal use by the marshalling/unmarshalling code: decode(bytes) Accept a base64 bytes object and decode it as the instance’s new data. enc

_makeResult() This method returns the instance of TestResult used by run(). It is not intended to be called directly, but can be overridden in subclasses to provide a custom TestResult. _makeResult() instantiates the class or callable passed in the TextTestRunner constructor as the resultclass argument. It defaults to TextTestResult if no resultclass is provided. The result class is instantiated with the following arguments: stream, descriptions, verbosity

xmlparser.buffer_size The size of the buffer used when buffer_text is true. A new buffer size can be set by assigning a new integer value to this attribute. When the size is changed, the buffer will be flushed.

Request.host The URI authority, typically a host, but may also contain a port separated by a colon.
