turtle.ht() Make the turtle invisible. It’s a good idea to do this while you’re in the middle of doing some complex drawing, because hiding the turtle speeds up the drawing observably. >>> turtle.hideturtle()

tracemalloc.start(nframe: int=1) Start tracing Python memory allocations: install hooks on Python memory allocators. Collected tracebacks of traces will be limited to nframe frames. By default, a trace of a memory block only stores the most recent frame: the limit is 1. nframe must be greater or equal to 1. Storing more than 1 frame is only useful to compute statistics grouped by 'traceback' or to compute cumulative statistics: see the Snapshot.compare_to() and Snapshot.statistics() methods.

AbstractEventLoop.remove_signal_handler(sig) Remove a handler for a signal. Return True if a signal handler was removed, False if not.

kevent.flags Filter action. Constant Meaning KQ_EV_ADD Adds or modifies an event KQ_EV_DELETE Removes an event from the queue KQ_EV_ENABLE Permitscontrol() to returns the event KQ_EV_DISABLE Disablesevent KQ_EV_ONESHOT Removes event after first occurrence KQ_EV_CLEAR Reset the state after an event is retrieved KQ_EV_SYSFLAGS internal event KQ_EV_FLAG1 internal event KQ_EV_EOF Filter specific EOF condition KQ_EV_ERROR See return values

re.compile(pattern, flags=0) Compile a regular expression pattern into a regular expression object, which can be used for matching using its match() and search() methods, described below. The expression’s behaviour can be modified by specifying a flags value. Values can be any of the following variables, combined using bitwise OR (the | operator). The sequence prog = re.compile(pattern) result = prog.match(string) is equivalent to result = re.match(pattern, string) but using re.compile() a

class pickle.Unpickler(file, *, fix_imports=True, encoding="ASCII", errors="strict") This takes a binary file for reading a pickle data stream. The protocol version of the pickle is detected automatically, so no protocol argument is needed. The argument file must have two methods, a read() method that takes an integer argument, and a readline() method that requires no arguments. Both methods should return bytes. Thus file can be an on-disk file object opened for binary reading, an io.BytesIO

float.hex() Return a representation of a floating-point number as a hexadecimal string. For finite floating-point numbers, this representation will always include a leading 0x and a trailing p and exponent.

class ctypes._FuncPtr Base class for C callable foreign functions. Instances of foreign functions are also C compatible data types; they represent C function pointers. This behavior can be customized by assigning to special attributes of the foreign function object. restype Assign a ctypes type to specify the result type of the foreign function. Use None for void, a function not returning anything. It is possible to assign a callable Python object that is not a ctypes type, in this case t

createLock() This method returns None for the lock, since there is no underlying I/O to which access needs to be serialized.

class code.InteractiveConsole(locals=None, filename="") Closely emulate the behavior of the interactive Python interpreter. This class builds on InteractiveInterpreter and adds prompting using the familiar sys.ps1 and sys.ps2, and input buffering.
