A token object is basically a (type, value) tuple. The valid types are EOF, EOL, WHITESPACE, IDENTIFIER, QUOTED_STRING, COMMENT, and DELIMITER. file: The file to tokenize ungotten_char: The most recently ungotten character, or None. ungotten_token: The most recently ungotten token, or None. multiline: The current multiline level. This value is increased by one every time a '(' delimiter is read, and decreased by one every time a ')' delimiter is read. quoting: This variable is true if the tokenizer is currently reading a quoted string. eof: This variable is true if the tokenizer has encountered EOF. delimiters: The current delimiter dictionary. line_number: The current line number filename: A filename that will be returned by the where() method.
