The input for Python's parser generator is in the Python source
distribution, file Grammar/Grammar.

Note that block structure is denoted *by* indentation in Python source, and
there are no "curly braces" (or other visible "begin block"/"end block"
tokens).  In the grammar, INDENT and DEDENT are the tokens generated by the
lexer when a change in indentation level (from the indentation of the
previous statement) is seen.
