class tkinter.Tk(screenName=None, baseName=None, className='Tk', useTk=1) The Tk class is instantiated without arguments. This creates a toplevel widget of Tk which usually is the main window of an application. Each instance has its own associated Tcl interpreter.

__delitem__(key) discard(key) These methods immediately delete the message. The MH convention of marking a message for deletion by prepending a comma to its name is not used.

class typing.Tuple Tuple type; Tuple[X, Y] is the type of a tuple of two items with the first item of type X and the second of type Y. Example: Tuple[T1, T2] is a tuple of two elements corresponding to type variables T1 and T2. Tuple[int, float, str] is a tuple of an int, a float and a string. To specify a variable-length tuple of homogeneous type, use literal ellipsis, e.g. Tuple[int, ...].

assertTupleEqual(first, second, msg=None) Tests that two lists or tuples are equal. If not, an error message is constructed that shows only the differences between the two. An error is also raised if either of the parameters are of the wrong type. These methods are used by default when comparing lists or tuples with assertEqual(). New in version 3.1.

time.clock_settime(clk_id, time) Set the time of the specified clock clk_id. Availability: Unix. New in version 3.3.

linecache.lazycache(filename, module_globals) Capture enough detail about a non-file-based module to permit getting its lines later via getline() even if module_globals is None in the later call. This avoids doing I/O until a line is actually needed, without having to carry the module globals around indefinitely. New in version 3.5.

tabs() Returns a list of windows managed by the notebook.

Element.getElementsByTagNameNS(namespaceURI, localName) Same as equivalent method in the Document class.

time.strftime(format[, t]) Convert a tuple or struct_time representing a time as returned by gmtime() or localtime() to a string as specified by the format argument. If t is not provided, the current time as returned by localtime() is used. format must be a string. ValueError is raised if any field in t is outside of the allowed range. 0 is a legal argument for any position in the time tuple; if it is normally illegal the value is forced to a correct one. The following directives can be embe

clear() Remove all items from the dictionary.
