winreg.OpenKeyEx(key, sub_key, reserved=0, access=KEY_READ) Opens the specified key, returning a handle object. key is an already open key, or one of the predefined HKEY_* constants. sub_key is a string that identifies the sub_key to open. reserved is a reserved integer, and must be zero. The default is zero. access is an integer that specifies an access mask that describes the desired security access for the key. Default is KEY_READ. See Access Rights for other allowed values. The result is

tobytes() Return the data in the buffer as a bytestring. This is equivalent to calling the bytes constructor on the memoryview. >>> m = memoryview(b"abc") >>> m.tobytes() b'abc' >>> bytes(m) b'abc' For non-contiguous arrays the result is equal to the flattened list representation with all elements converted to bytes. tobytes() supports all format strings, including those that are not in struct module syntax.

HTTPConnection.request(method, url, body=None, headers={}) This will send a request to the server using the HTTP request method method and the selector url. If body is specified, the specified data is sent after the headers are finished. It may be a string, a bytes-like object, an open file object, or an iterable of bytes-like objects. If body is a string, it is encoded as ISO-8859-1, the default for HTTP. If it is a bytes-like object the bytes are sent as is. If it is a file object, the con

Source code: Lib/idlelib/ IDLE is Python’s Integrated Development and Learning Environment. IDLE has the following features: coded in 100% pure Python, using the tkinter GUI toolkit cross-platform: works mostly the same on Windows, Unix, and Mac OS X Python shell window (interactive interpreter) with colorizing of code input, output, and error messages multi-window text editor with multiple undo, Python colorizing, smart indent, call tips, auto completion, and other features search within any w

getbuffer() Return a readable and writable view over the contents of the buffer without copying them. Also, mutating the view will transparently update the contents of the buffer: >>> b = io.BytesIO(b"abcdef") >>> view = b.getbuffer() >>> view[2:4] = b"56" >>> b.getvalue() b'ab56ef' Note As long as the view exists, the BytesIO object cannot be resized or closed. New in version 3.2.

emit() Pickles the record’s attribute dictionary and writes it to the socket in binary format. If there is an error with the socket, silently drops the packet. If the connection was previously lost, re-establishes the connection. To unpickle the record at the receiving end into a LogRecord, use the makeLogRecord() function.

sys.version_info A tuple containing the five components of the version number: major, minor, micro, releaselevel, and serial. All values except releaselevel are integers; the release level is 'alpha', 'beta', 'candidate', or 'final'. The version_info value corresponding to the Python version 2.0 is (2, 0, 0, 'final', 0). The components can also be accessed by name, so sys.version_info[0] is equivalent to sys.version_info.major and so on. Changed in version 3.1: Added named component attribu

importlib.util.find_spec(name, package=None) Find the spec for a module, optionally relative to the specified package name. If the module is in sys.modules, then sys.modules[name].__spec__ is returned (unless the spec would be None or is not set, in which case ValueError is raised). Otherwise a search using sys.meta_path is done. None is returned if no spec is found. If name is for a submodule (contains a dot), the parent module is automatically imported. name and package work the same as fo

window.refresh([pminrow, pmincol, sminrow, smincol, smaxrow, smaxcol]) Update the display immediately (sync actual screen with previous drawing/deleting methods). The 6 optional arguments can only be specified when the window is a pad created with newpad(). The additional parameters are needed to indicate what part of the pad and screen are involved. pminrow and pmincol specify the upper left-hand corner of the rectangle to be displayed in the pad. sminrow, smincol, smaxrow, and smaxcol spec

Cookie.secure True if cookie should only be returned over a secure connection.
