turtle.screensize(canvwidth=None, canvheight=None, bg=None) Parameters: canvwidth – positive integer, new width of canvas in pixels canvheight – positive integer, new height of canvas in pixels bg – colorstring or color-tuple, new background color If no arguments are given, return current (canvaswidth, canvasheight). Else resize the canvas the turtles are drawing on. Do not alter the drawing window. To observe hidden parts of the canvas, use the scrollbars. With this method, one can m

bind_partial(*args, **kwargs) Works the same way as Signature.bind(), but allows the omission of some required arguments (mimics functools.partial() behavior.) Returns BoundArguments, or raises a TypeError if the passed arguments do not match the signature.

origin

Cookie.port String representing a port or a set of ports (eg. ‘80’, or ‘80,8080’), or None.

sqlite3.complete_statement(sql) Returns True if the string sql contains one or more complete SQL statements terminated by semicolons. It does not verify that the SQL is syntactically correct, only that there are no unclosed string literals and the statement is terminated by a semicolon. This can be used to build a shell for SQLite, as in the following example: # A minimal SQLite shell for experiments import sqlite3 con = sqlite3.connect(":memory:") con.isolation_level = None cur = con.curs

MimeTypes.encodings_map Dictionary mapping filename extensions to encoding types. This is initially a copy of the global encodings_map defined in the module.

math.fsum(iterable) Return an accurate floating point sum of values in the iterable. Avoids loss of precision by tracking multiple intermediate partial sums: >>> sum([.1, .1, .1, .1, .1, .1, .1, .1, .1, .1]) 0.9999999999999999 >>> fsum([.1, .1, .1, .1, .1, .1, .1, .1, .1, .1]) 1.0 The algorithm’s accuracy depends on IEEE-754 arithmetic guarantees and the typical case where the rounding mode is half-even. On some non-Windows builds, the underlying C library uses extended pr

traceback.print_last(limit=None, file=None, chain=True) This is a shorthand for print_exception(sys.last_type, sys.last_value, sys.last_traceback, limit, file, chain). In general it will work only after an exception has reached an interactive prompt (see sys.last_type).

ctypes.create_string_buffer(init_or_size, size=None) This function creates a mutable character buffer. The returned object is a ctypes array of c_char. init_or_size must be an integer which specifies the size of the array, or a bytes object which will be used to initialize the array items. If a bytes object is specified as first argument, the buffer is made one item larger than its length so that the last element in the array is a NUL termination character. An integer can be passed as second

Node.hasChildNodes() Returns true if the node has any child nodes.
