os.getenv(key, default=None) Return the value of the environment variable key if it exists, or default if it doesn’t. key, default and the result are str. On Unix, keys and values are decoded with sys.getfilesystemencoding() and 'surrogateescape' error handler. Use os.getenvb() if you would like to use a different encoding. Availability: most flavors of Unix, Windows.

time.ctime([secs]) Convert a time expressed in seconds since the epoch to a string representing local time. If secs is not provided or None, the current time as returned by time() is used. ctime(secs) is equivalent to asctime(localtime(secs)). Locale information is not used by ctime().

server_version This will be "SimpleHTTP/" + __version__, where __version__ is defined at the module level.

Morsel.output(attrs=None, header='Set-Cookie:') Return a string representation of the Morsel, suitable to be sent as an HTTP header. By default, all the attributes are included, unless attrs is given, in which case it should be a list of attributes to use. header is by default "Set-Cookie:".

col_offset Instances of ast.expr and ast.stmt subclasses have lineno and col_offset attributes. The lineno is the line number of source text (1-indexed so the first line is line 1) and the col_offset is the UTF-8 byte offset of the first token that generated the node. The UTF-8 offset is recorded because the parser uses UTF-8 internally.

Logger.makeRecord(name, lvl, fn, lno, msg, args, exc_info, func=None, extra=None, sinfo=None) This is a factory method which can be overridden in subclasses to create specialized LogRecord instances.

xml.parsers.expat.errors.codes A dictionary mapping numeric error codes to their string descriptions. New in version 3.2.

csv.field_size_limit([new_limit]) Returns the current maximum field size allowed by the parser. If new_limit is given, this becomes the new limit.

timezone.dst(dt) Always returns None.

exception shutil.Error This exception collects exceptions that are raised during a multi-file operation. For copytree(), the exception argument is a list of 3-tuples (srcname, dstname, exception).
