Lib/tokenize.py

-"""tokenize.py (Ka-Ping Yee, 4 March 1997)
-
-This module compiles a regular expression that recognizes Python tokens
-in individual lines of text.  The regular expression handles everything
-except indentation, continuations, and triple-quoted strings.  The function
-'tokenize.tokenize()' takes care of these things for streams of text.  It
-accepts a file-like object and a function, uses the readline() method to
-scan the file, and calls the function called once for each token found
-passing its type, a string containing the token, the line number, the line,
-and the starting and ending positions of the token within the line.
-It is designed to match the working of the Python tokenizer exactly."""
