I think this is overkill for what I'm trying to do, could you please refer to what I just wrote luke? That might make things simpler.. <br><br><div><span class="gmail_quote">On 10/18/06, <b class="gmail_sendername">John Fouhy

<br><br> If nothing in directoryList matches item, how do I find the<br>element of directoryList that should have matched?<br><br>This is a bit tricky, because you need to define exactly what results<br>you expect.<br>
<br>(for example, suppose limitedLineList contained 'SL_39.sdr' and<br>directoryList had 'SL39.sdr'. Is that something that should be a<br>match?)<br><br>Possibly you could do this:<br><br>def match(item, lst):<br> """ See if item is present in lst.
<br><br> output :: bool<br> """<br> return item in lst<br><br>def near_match(item, lst):<br> """ See if item is similar to something in lst. Currently, we just<br>match case-insensitive.
<br><br> output :: first matching element of lst, or None<br> """<br> for item2 in lst:<br> if item.upper() == item2.upper():<br> return item2<br> return None<br><br>for item in limitedLineList:
<br> if match(item, directoryList):<br> print '%20s%20s%20s' % ('Match!', item, item)<br> else:<br> item2 = near_match(item, directoryList)<br> if item2:<br> print '%20s%20s%20s' % ('Fail!', item, item2)
<br> else:<br> print '%20s%20s%20s' % ('Fail!', item, '????')<br><br>You can modify near_match if you have some other definition of what<br>you want it to return.<br><br>--<br>John.<br>_______________________________________________
