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.

f: The file to tokenize. The default is sys.stdin.
This parameter may also be a string, in which case the tokenizer
will take its input from the contents of the string.

will return.
