finish_request() Actually processes the request by instantiating RequestHandlerClass and calling its handle() method.

subTest(msg=None, **params) Return a context manager which executes the enclosed code block as a subtest. msg and params are optional, arbitrary values which are displayed whenever a subtest fails, allowing you to identify them clearly. A test case can contain any number of subtest declarations, and they can be arbitrarily nested. See Distinguishing test iterations using subtests for more information. New in version 3.4.

epoll.fileno() Return the file descriptor number of the control fd.

os.lstat(path, *, dir_fd=None) Perform the equivalent of an lstat() system call on the given path. Similar to stat(), but does not follow symbolic links. Return a stat_result object. On platforms that do not support symbolic links, this is an alias for stat(). As of Python 3.3, this is equivalent to os.stat(path, dir_fd=dir_fd, follow_symlinks=False). This function can also support paths relative to directory descriptors. See also The stat() function. Changed in version 3.2: Added support

class typing.Generator(Iterator[T_co], Generic[T_co, T_contra, V_co]) A generator can be annotated by the generic type Generator[YieldType, SendType, ReturnType]. For example: def echo_round() -> Generator[int, float, str]: sent = yield 0 while sent >= 0: sent = yield round(sent) return 'Done' Note that unlike many other generics in the typing module, the SendType of Generator behaves contravariantly, not covariantly or invariantly. If your generator will only yiel

class unittest.mock.Mock(spec=None, side_effect=None, return_value=DEFAULT, wraps=None, name=None, spec_set=None, unsafe=False, **kwargs) Create a new Mock object. Mock takes several optional arguments that specify the behaviour of the Mock object: spec: This can be either a list of strings or an existing object (a class or instance) that acts as the specification for the mock object. If you pass in an object then a list of strings is formed by calling dir on the object (excluding unsupport

class asyncio.AbstractEventLoopPolicy Event loop policy. get_event_loop() Get the event loop for the current context. Returns an event loop object implementing the AbstractEventLoop interface. Raises an exception in case no event loop has been set for the current context and the current policy does not specify to create one. It must never return None. set_event_loop(loop) Set the event loop for the current context to loop. new_event_loop() Create and return a new event loop ob

os.execvp(file, args) os.execvpe(file, args, env) These functions all execute a new program, replacing the current process; they do not return. On Unix, the new executable is loaded into the current process, and will have the same process id as the caller. Errors will be reported as OSError exceptions. The current process is replaced immediately. Open file objects and descriptors are not flushed, so if there may be data buffered on these open files, you should flush them using sys.stdout.flus

class complex([real[, imag]]) Return a complex number with the value real + imag*1j or convert a string or number to a complex number. If the first parameter is a string, it will be interpreted as a complex number and the function must be called without a second parameter. The second parameter can never be a string. Each argument may be any numeric type (including complex). If imag is omitted, it defaults to zero and the constructor serves as a numeric conversion like int and float. If both

_b_base_ Sometimes ctypes data instances do not own the memory block they contain, instead they share part of the memory block of a base object. The _b_base_ read-only member is the root ctypes object that owns the memory block.
