class asyncio.BaseSubprocessTransport get_pid() Return the subprocess process id as an integer. get_pipe_transport(fd) Return the transport for the communication pipe corresponding to the integer file descriptor fd: 0: readable streaming transport of the standard input (stdin), or None if the subprocess was not created with stdin=PIPE 1: writable streaming transport of the standard output (stdout), or None if the subprocess was not created with stdout=PIPE 2: writable streaming

signal.sigtimedwait(sigset, timeout) Like sigwaitinfo(), but takes an additional timeout argument specifying a timeout. If timeout is specified as 0, a poll is performed. Returns None if a timeout occurs. Availability: Unix (see the man page sigtimedwait(2) for further information). See also pause(), sigwait() and sigwaitinfo(). New in version 3.3. Changed in version 3.5: The function is now retried with the recomputed timeout if interrupted by a signal not in sigset and the signal handle

find_loader(fullname) A legacy method for finding a loader for the specified module. Returns a 2-tuple of (loader, portion) where portion is a sequence of file system locations contributing to part of a namespace package. The loader may be None while specifying portion to signify the contribution of the file system locations to a namespace package. An empty list can be used for portion to signify the loader is not part of a namespace package. If loader is None and portion is the empty list t

sys.getprofile() Get the profiler function as set by setprofile().

UUID.int The UUID as a 128-bit integer.

winreg.SaveKey(key, file_name) Saves the specified key, and all its subkeys to the specified file. key is an already open key, or one of the predefined HKEY_* constants. file_name is the name of the file to save registry data to. This file cannot already exist. If this filename includes an extension, it cannot be used on file allocation table (FAT) file systems by the LoadKey() method. If key represents a key on a remote computer, the path described by file_name is relative to the remote com

class decimal.Context(prec=None, rounding=None, Emin=None, Emax=None, capitals=None, clamp=None, flags=None, traps=None) Creates a new context. If a field is not specified or is None, the default values are copied from the DefaultContext. If the flags field is not specified or is None, all flags are cleared. prec is an integer in the range [1, MAX_PREC] that sets the precision for arithmetic operations in the context. The rounding option is one of the constants listed in the section Rounding

winreg.LoadKey(key, sub_key, file_name) Creates a subkey under the specified key and stores registration information from a specified file into that subkey. key is a handle returned by ConnectRegistry() or one of the constants HKEY_USERS or HKEY_LOCAL_MACHINE. sub_key is a string that identifies the subkey to load. file_name is the name of the file to load registry data from. This file must have been created with the SaveKey() function. Under the file allocation table (FAT) file system, the

sys.last_value sys.last_traceback These three variables are not always defined; they are set when an exception is not handled and the interpreter prints an error message and a stack traceback. Their intended use is to allow an interactive user to import a debugger module and engage in post-mortem debugging without having to re-execute the command that caused the error. (Typical use is import pdb; pdb.pm() to enter the post-mortem debugger; see pdb module for more information.) The meaning of

SSLContext.wrap_bio(incoming, outgoing, server_side=False, server_hostname=None) Create a new SSLObject instance by wrapping the BIO objects incoming and outgoing. The SSL routines will read input data from the incoming BIO and write data to the outgoing BIO. The server_side and server_hostname parameters have the same meaning as in SSLContext.wrap_socket().
