Bob,

Using your suggestion, I did a little test on a modified version of my pipe
dictionary:

pipeDict = \
{('lineEdit001','Steel(Std)','1/2"',.85): .622, 
('lineEdit002','Steel(Std)','3/4"',1.13): .824,
('lineEdit003','Steel(Std)','1"',1.678): 1.049,
('lineEdit004','Steel(Std)','1-1/4"',2.272): 1.38,
('lineEdit005','Steel(Std)','1-1/2"',2.717): 1.61,
('lineEdit006','Steel(Std)','2"',3.652): 2.067, 
('lineEdit007','Steel(Std)','2-1/2"',5.79): 2.469, 
('lineEdit008','Steel(Std)','3"',7.57): 3.068, 
('lineEdit009','Steel(Std)','3-1/2"',9.11): 3.548, 
('lineEdit010','Steel(Std)','4"',10.79): 4.026, 
('lineEdit011','Steel(Std)','5"',14.62): 5.047, 
('lineEdit012','Steel(Std)','6"',18.97): 6.065, 
('lineEdit013','Steel(Std)','8"',28.55): 7.981, 
('lineEdit014','Steel(Std)','10"',40.48): 10.02}

And using these functions again (slightly modified):

def someReport():
    report = []
    for name, typ, size, weight in pipeDict:
        report.append((name,typ,size,weight))
        report.sort()
        newReport = filterPipeData(report)
    print newReport

def filterPipeData(data):
    """idea for list comp, from Kent"
    return [(typ,size,weight) for name, typ, size, weight in data]

It works perfectly! Thank You! Notice how I removed the other "size" number
that was in the previous dict.

You mentioned that the #'s I use, will have to be the same length. My GUI uses
100 lineEdits, so a numbering scheme like 001 - 100 should sort correctly (I
guess). I haven't tried it on the whole dictionary yet, but I will! Changing
the numbering of the lineEdits, is *not* a problem at all.

Thanks again,

Bill
