lzma.is_check_supported(check) Returns true if the given integrity check is supported on this system. CHECK_NONE and CHECK_CRC32 are always supported. CHECK_CRC64 and CHECK_SHA256 may be unavailable if you are using a version of liblzma that was compiled with a limited feature set.

run(cmd) Execute the command and gather statistics from the execution with the current tracing parameters. cmd must be a string or code object, suitable for passing into exec().

shape A tuple of integers the length of ndim giving the shape of the memory as an N-dimensional array. Changed in version 3.3: An empty tuple instead of None when ndim = 0.

class socketserver.UnixStreamServer(server_address, RequestHandlerClass, bind_and_activate=True) class socketserver.UnixDatagramServer(server_address, RequestHandlerClass, bind_and_activate=True) These more infrequently used classes are similar to the TCP and UDP classes, but use Unix domain sockets; they’re not available on non-Unix platforms. The parameters are the same as for TCPServer.

output_difference(example, got, optionflags) Return a string describing the differences between the expected output for a given example (example) and the actual output (got). optionflags is the set of option flags used to compare want and got.

Request.data The entity body for the request, or None if not specified. Changed in version 3.4: Changing value of Request.data now deletes “Content-Length” header if it was previously set or calculated.

devpoll.register(fd[, eventmask]) Register a file descriptor with the polling object. Future calls to the poll() method will then check whether the file descriptor has any pending I/O events. fd can be either an integer, or an object with a fileno() method that returns an integer. File objects implement fileno(), so they can also be used as the argument. eventmask is an optional bitmask describing the type of events you want to check for. The constants are the same that with poll() object. T

returncode Return code of the process when it exited. A None value indicates that the process has not terminated yet. A negative value -N indicates that the child was terminated by signal N (Unix only).

logging.makeLogRecord(attrdict) Creates and returns a new LogRecord instance whose attributes are defined by attrdict. This function is useful for taking a pickled LogRecord attribute dictionary, sent over a socket, and reconstituting it as a LogRecord instance at the receiving end.

_flush() Force buffered data to be transmitted to the client. It’s okay if this method is a no-op (i.e., if _write() actually sends the data).
