regex.fullmatch(string[, pos[, endpos]]) If the whole string matches this regular expression, return a corresponding match object. Return None if the string does not match the pattern; note that this is different from a zero-length match. The optional pos and endpos parameters have the same meaning as for the search() method. >>> pattern = re.compile("o[gh]") >>> pattern.fullmatch("dog") # No match as "o" is not at the start of "dog". >>> pattern.fullmatch("og

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

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.

find_spec(fullname, path, target=None) An abstract method for finding a spec for the specified module. If this is a top-level import, path will be None. Otherwise, this is a search for a subpackage or module and path will be the value of __path__ from the parent package. If a spec cannot be found, None is returned. When passed in, target is a module object that the finder may use to make a more educated about what spec to return. New in version 3.4.

shutil.move(src, dst, copy_function=copy2) Recursively move a file or directory (src) to another location (dst) and return the destination. If the destination is an existing directory, then src is moved inside that directory. If the destination already exists but is not a directory, it may be overwritten depending on os.rename() semantics. If the destination is on the current filesystem, then os.rename() is used. Otherwise, src is copied to dst using copy_function and then removed. In case o

filename2 For exceptions that involve a file system path (such as open() or os.unlink()), filename is the file name passed to the function. For functions that involve two file system paths (such as os.rename()), filename2 corresponds to the second file name passed to the function.

codecs.xmlcharrefreplace_errors(exception) Implements the 'xmlcharrefreplace' error handling (for encoding with text encodings only): the unencodable character is replaced by an appropriate XML character reference.

heapq.heappop(heap) Pop and return the smallest item from the heap, maintaining the heap invariant. If the heap is empty, IndexError is raised. To access the smallest item without popping it, use heap[0].

SSLSocket.unwrap() Performs the SSL shutdown handshake, which removes the TLS layer from the underlying socket, and returns the underlying socket object. This can be used to go from encrypted operation over a connection to unencrypted. The returned socket should always be used for further communication with the other side of the connection, rather than the original socket.

time.process_time() Return the value (in fractional seconds) of the sum of the system and user CPU time of the current process. It does not include time elapsed during sleep. It is process-wide by definition. The reference point of the returned value is undefined, so that only the difference between the results of consecutive calls is valid. New in version 3.3.
