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.

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.

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.

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

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.

tag_configure(tagname, option=None, **kw) Query or modify the options for the specified tagname. If kw is not given, returns a dict of the option settings for tagname. If option is specified, returns the value for that option for the specified tagname. Otherwise, sets the options to the corresponding values for the given tagname.

TarInfo.isblk() Return True if it is a block device.

classmethod TarInfo.frombuf(buf, encoding, errors) Create and return a TarInfo object from string buffer buf. Raises HeaderError if the buffer is invalid.

str.split(sep=None, maxsplit=-1) Return a list of the words in the string, using sep as the delimiter string. If maxsplit is given, at most maxsplit splits are done (thus, the list will have at most maxsplit+1 elements). If maxsplit is not specified or -1, then there is no limit on the number of splits (all possible splits are made). If sep is given, consecutive delimiters are not grouped together and are deemed to delimit empty strings (for example, '1,,2'.split(',') returns ['1', '', '2'])
