MoinMoin - Python Source Parser

Title: Colorize Python source using the built-in tokenizer

Submitter: Jurgen Hermann Last Updated:2001/04/06

Version no:1.2


This code is part of MoinMoin ( and converts Python source code to HTML markup, rendering comments, keywords, operators, numeric and string literals in different colors.

It shows how to use the built-in keyword, token and tokenize modules to scan Python source code and re-emit it with no changes to its original formatting (which is the hard part).


class IPython.PyColorize.Parser(color_table=None, out=<open file '<stdout>', mode 'w' at 0x403b2078>)

Format colored Python source.


Create a parser with a specified color table and output channel.

Call format() to process code.


Parse and send the colored source.

If out and scheme are not specified, the defaults (given to constructor) are used.

out should be a file-type object. Optionally, out can be given as the string ‘str’ and the parser will automatically return the output in a string.


Run as a command-line script: colorize a python file or stdin using ANSI color escapes and print to stdout.


  • argv(None): a list of strings like sys.argv[1:] giving the command-line arguments. If None, use sys.argv[1:].
