Description:
 def _parse_path(self, path):
 """Parse ``path`` into segments. Paths must start with a WORD (i.e., a top level Django setting name). Path segments are separated by dots. Compound path segments (i.e., a name with a dot in it) can be grouped inside parentheses. Examples:: ['WORD'] ['WORD', 'x'] ['WORD', 'x'] ['WORD', 'x.y'] ['WORD', 'x.y', 'z'] ['WORD', 0, 'z'] ['WORD', '0', 'z'] ['WORD', '0X', 'z'] An example of where compound names are actually useful is in logger settings:: LOGGING.loggers.(package.module).handlers = ["console"] LOGGING.loggers.(package.module).level = "DEBUG" Paths may also contain interpolation groups. Dotted names in these groups will not be split (so there's no need to group them inside parentheses):
: ['WORD', '{{x}}'] ['WORD', '{{x.y}}'] ['WORD', '{{x.y.z}}XYZ'] Interpolation groups *can* be wrapped in parentheses, but doing so is redundant:: ['WORD', '{{x.y.z}}XYZ'] Any segment that A) looks like an int and B) does *not* contain that start with a leading "0" followed by other digits will not be converted.
