"token" --- Constants used with Python parse trees
**************************************************

**Source code:** Lib/token.py

======================================================================

This module provides constants which represent the numeric values of
leaf nodes of the parse tree (terminal tokens).  Refer to the file
"Grammar/Tokens" in the Python distribution for the definitions of the
names in the context of the language grammar.  The specific numeric
values which the names map to may change between Python versions.

The module also provides a mapping from numeric codes to names and
some functions.  The functions mirror definitions in the Python C
header files.

token.tok_name

   Dictionary mapping the numeric values of the constants defined in
   this module back to name strings, allowing more human-readable
   representation of parse trees to be generated.

token.ISTERMINAL(x)

   Return "True" for terminal token values.

token.ISNONTERMINAL(x)

   Return "True" for non-terminal token values.

token.ISEOF(x)

   Return "True" if *x* is the marker indicating the end of input.

The following token type values aren't used by the C tokenizer but are
needed for the "tokenize" module.

token.COMMENT

   Token value used to indicate a comment.

token.NL

   Token value used to indicate a non-terminating newline.  The
   "NEWLINE" token indicates the end of a logical line of Python code;
   "NL" tokens are generated when a logical line of code is continued
   over multiple physical lines.

token.ENCODING

   Token value that indicates the encoding used to decode the source
   bytes into text. The first token returned by "tokenize.tokenize()"
   will always be an "ENCODING" token.

token.TYPE_COMMENT

   Token value indicating that a type comment was recognized.  Such
   tokens are only produced when "ast.parse()" is invoked with
   "type_comments=True".

3.5 sürümünde değişti: Added "AWAIT" and "ASYNC" tokens.

3.7 sürümünde değişti: Added "COMMENT", "NL" and "ENCODING" tokens.

3.7 sürümünde değişti: Removed "AWAIT" and "ASYNC" tokens. "async" and
"await" are now tokenized as "NAME" tokens.

3.8 sürümünde değişti: Added "TYPE_COMMENT", "TYPE_IGNORE",
"COLONEQUAL". Added "AWAIT" and "ASYNC" tokens back (they're needed to
support parsing older Python versions for "ast.parse()" with
"feature_version" set to 6 or lower).
