This prevents package-internal imports from parser conflicting with any user-defined module named parser, which is quite frequent when writing parsers. This feature is available since Python 2.5, per PEP 0328.
This is for python3 compat. basestring no longer exists in python3.
These clutter up otherwise empty output for users.
This is a "new" feature in PLY, where single-character tokens can be specified
directly by value instead of going through a name. For example, if in the
lexer there is:
literals = ",.()[]{}"
then rules in the grammar can have, for example:
expr : '(' {expr} ')'
