Hi all!

I'm doing some work with python and forums and I've created an app that will reload previous form data that a user has entered and saved to a file so they may edit it and re-save the changes. Among that data are several select boxs. I found that reloading the values for those were trickey and the method I used was cluckey and large. I was wondering if anybody knew a more intelegent/elegant way of doing this.

Basically, I've sucked the value back down from the file and, depending on it's value built a html string that will have the value selected. Then I print out the page with that string. Likea so:

(Toggle Plain Text)

.
.
.
#loaded from xml file
theValue =  n.childNodes[0].nodeValue

#html string to be the reloaded select box
htmlString = """
Please select one:
<select>
<option value="1"
"""

if (theValue == "1"):
   htmlString = htmlString + """ selected="selected">1</option>
                                 <option value="2">2</option>
                           """
else:
   htmlString = htmlString + """ >1</option>
                               <option value="2" selected="selected">2</option>
                         """

print myPage % {'select': htmlString}

I did out this example with only two values, but I'm actually doing it for a 24 hr clock, thus there are 24 values for the hour method and then another 7 for the minutes (increments of 10). So, as you can imagine, the code gets really big really fast. Any thoughts? I hope my example is clear enough.

Thanks.
