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 "<" and ">".

example csv file row:
"FIXED","All","Enable <audio> entry"

and I want to replace <audio> with <audio> 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 <audio> 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.
