replacing characters within a string

[John Smith]

Hi,

I coded a python script that lets me parse a csv file into html code
with a certain format, but I would like to replace every "<" and ">"
character that appears within each column entry of the csv file (they
are parsed as strings) with the html equivalents of "&lt;" and "&gt;".

example csv file row:
"FIXED","All"," Enable <audioentry"

and I want to replace <audiowith &lt;audio&gt ; before I do a

"<p>This is a " + str(array[0]) + " bug that applies to " +
str(array[1]) + " platforms and has the description: " + str(array[2]) +
".</p>"

to get the following html code:

<p>This is a FIXED bug that applies to All platforms and has the
description: Enable &lt;audio&gt ; entry.</p>

(sometimes < appears twice or thrice and sometimes only appears so
they are not necessarily appearing together, e.g. -instead of <something>)

How should I go about doing it?

Regards.

You want the cgi.escape() function -

FYI: Python strings do have a .replace method,
but for the above application

You want the cgi.escape() function -
http://docs.python.org/library/cgi.html#cgi.escape

*is* what you should use, as it will do all needed replacements in one call.
