msilib.init_database(name, schema, ProductName, ProductCode, ProductVersion, Manufacturer) Create and return a new database name, initialize it with schema, and set the properties ProductName, ProductCode, ProductVersion, and Manufacturer. schema must be a module object containing tables and _Validation_records attributes; typically, msilib.schema should be used. The database will contain just the schema and the validation records when this function returns.

itemsize The size in bytes of each element of the memoryview: >>> import array, struct >>> m = memoryview(array.array('H', [32000, 32001, 32002])) >>> m.itemsize 2 >>> m[0] 32000 >>> struct.calcsize('H') == m.itemsize True

get_from() Return a string representing the “From ” line that marks the start of the message in an mbox mailbox. The leading “From ” and the trailing newline are excluded.

range(stop) range(start, stop[, step]) Rather than being a function, range is actually an immutable sequence type, as documented in Ranges and Sequence Types — list, tuple, range.

socket.gethostname() Return a string containing the hostname of the machine where the Python interpreter is currently executing. Note: gethostname() doesn’t always return the fully qualified domain name; use getfqdn() for that.

AbstractEventLoop.add_reader(fd, callback, *args) Start watching the file descriptor for read availability and then call the callback with specified arguments. Use functools.partial to pass keywords to the callback.

os.path.normcase(path) Normalize the case of a pathname. On Unix and Mac OS X, this returns the path unchanged; on case-insensitive filesystems, it converts the path to lowercase. On Windows, it also converts forward slashes to backward slashes. Raise a TypeError if the type of path is not str or bytes.

sysconfig.parse_config_h(fp[, vars]) Parse a config.h-style file. fp is a file-like object pointing to the config.h-like file. A dictionary containing name/value pairs is returned. If an optional dictionary is passed in as the second argument, it is used instead of a new dictionary, and updated with the values read in the file.

multiprocessing.Array(typecode_or_type, size_or_initializer, *, lock=True) Return a ctypes array allocated from shared memory. By default the return value is actually a synchronized wrapper for the array. typecode_or_type determines the type of the elements of the returned array: it is either a ctypes type or a one character typecode of the kind used by the array module. If size_or_initializer is an integer, then it determines the length of the array, and the array will be initially zeroed.

pty.spawn(argv[, master_read[, stdin_read]]) Spawn a process, and connect its controlling terminal with the current process’s standard io. This is often used to baffle programs which insist on reading from the controlling terminal. The functions master_read and stdin_read should be functions which read from a file descriptor. The defaults try to read 1024 bytes each time they are called. Changed in version 3.4: spawn() now returns the status value from os.waitpid() on the child process.
