clear() Remove all elements from the deque leaving it with length 0.

daemon The process’s daemon flag, a Boolean value. This must be set before start() is called. The initial value is inherited from the creating process. When a process exits, it attempts to terminate all of its daemonic child processes. Note that a daemonic process is not allowed to create child processes. Otherwise a daemonic process would leave its children orphaned if it gets terminated when its parent process exits. Additionally, these are not Unix daemons or services, they are normal pro

itertools.combinations(iterable, r) Return r length subsequences of elements from the input iterable. Combinations are emitted in lexicographic sort order. So, if the input iterable is sorted, the combination tuples will be produced in sorted order. Elements are treated as unique based on their position, not on their value. So if the input elements are unique, there will be no repeat values in each combination. Roughly equivalent to: def combinations(iterable, r): # combinations('ABCD',

turtle.getscreen() Return the TurtleScreen object the turtle is drawing on. TurtleScreen methods can then be called for that object. >>> ts = turtle.getscreen() >>> ts <turtle._Screen object at 0x...> >>> ts.bgcolor("pink")

read1() In BytesIO, this is the same as read().

class tkinter.tix.CheckList The CheckList widget displays a list of items to be selected by the user. CheckList acts similarly to the Tk checkbutton or radiobutton widgets, except it is capable of handling many more items than checkbuttons or radiobuttons.

st_rsize Real size of the file.

window.mvderwin(y, x) Move the window inside its parent window. The screen-relative parameters of the window are not changed. This routine is used to display different parts of the parent window at the same physical position on the screen.

operator.__or__(a, b) Return the bitwise or of a and b.

timeit.timeit(stmt='pass', setup='pass', timer=, number=1000000, globals=None) Create a Timer instance with the given statement, setup code and timer function and run its timeit() method with number executions. The optional globals argument specifies a namespace in which to execute the code. Changed in version 3.5: The optional globals parameter was added.
