os.supports_fd A Set object indicating which functions in the os module permit specifying their path parameter as an open file descriptor. Different platforms provide different functionality, and an option that might work on one might be unsupported on another. For consistency’s sakes, functions that support fd always allow specifying the parameter, but will raise an exception if the functionality is not actually available. To check whether a particular function permits specifying an open fi

difflib.IS_CHARACTER_JUNK(ch) Return true for ignorable characters. The character ch is ignorable if ch is a space or tab, otherwise it is not ignorable. Used as a default for parameter charjunk in ndiff().

The distutils package provides support for building and installing additional modules into a Python installation. The new modules may be either 100%-pure Python, or may be extension modules written in C, or may be collections of Python packages which include modules coded in both Python and C. Most Python users will not want to use this module directly, but instead use the cross-version tools maintained by the Python Packaging Authority. In particular, setuptools is an enhanced alternative to d

difflib.IS_LINE_JUNK(line) Return true for ignorable lines. The line line is ignorable if line is blank or contains a single '#', otherwise it is not ignorable. Used as a default for parameter linejunk in ndiff() in older versions.

get_nowait() Remove and return an item from the queue. Return an item if one is immediately available, else raise QueueEmpty.

class collections.defaultdict([default_factory[, ...]]) Returns a new dictionary-like object. defaultdict is a subclass of the built-in dict class. It overrides one method and adds one writable instance variable. The remaining functionality is the same as for the dict class and is not documented here. The first argument provides the initial value for the default_factory attribute; it defaults to None. All remaining arguments are treated the same as if they were passed to the dict constructor

isatty() Return True if the stream is interactive (i.e., connected to a terminal/tty device).

release() Release a semaphore, incrementing the internal counter by one. When it was zero on entry and another coroutine is waiting for it to become larger than zero again, wake up that coroutine.

turtle.setpos(x, y=None) turtle.setposition(x, y=None) Parameters: x – a number or a pair/vector of numbers y – a number or None If y is None, x must be a pair of coordinates or a Vec2D (e.g. as returned by pos()). Move turtle to an absolute position. If the pen is down, draw line. Do not change the turtle’s orientation. >>> tp = turtle.pos() >>> tp (0.00,0.00) >>> turtle.setpos(60,30) >>> turtle.pos() (60.00,30.00) >>> turtle.setpos((20,80)

socket.connect(address) Connect to a remote socket at address. (The format of address depends on the address family — see above.) If the connection is interrupted by a signal, the method waits until the connection completes, or raise a socket.timeout on timeout, if the signal handler doesn’t raise an exception and the socket is blocking or has a timeout. For non-blocking sockets, the method raises an InterruptedError exception if the connection is interrupted by a signal (or the exception ra
