xlrd cell background color

[patrick.waldo at gmail.com]

Hi all,

I am trying to figure out a way to read colors with xlrd, but I did
not understand the formatting.py module.  Basically, I want to sort
rows that are red or green.  My initial attempt discovered that
>>>print cell
text:u'test1.txt' (XF:22)
text:u'test2.txt' (XF:15)
text:u'test3.txt' (XF:15)
text:u'test4.txt' (XF:15)
text:u'test5.txt' (XF:23)

So, I thought that XF:22 represented my red highlighted row and XF:23
represented my green highlighted row.  However, that was not always
true.  If one row is blank and I only highlighted one row, I got:
>>>print cell
text:u'test1.txt' (XF:22)
text:u'test2.txt' (XF:22)
text:u'test3.txt' (XF:22)
text:u'test4.txt' (XF:22)
text:u'test5.txt' (XF:22)
empty:'' (XF:15)
text:u'test6.txt' (XF:22)
text:u'test7.txt' (XF:23)

Now NoFill is XF:22!  I am sure I am going about this the wrong way,
but I just want to store filenames into a dictionary based on whether
they are red or green.  Any ideas would be much appreciated.  My code
is below.

Best,
Patrick


filenames = {}
filenames.setdefault('GREEN',[])
filenames.setdefault('RED',[])

book = xlrd.open_workbook("/home/pwaldo2/work/workbench/
Summary.xls",formatting_info=True)
SumDoc = book.sheet_by_index(0)

n=1
while n<SumDoc.nrows:
    cell = SumDoc.cell(n,5)
    print cell
    filename = str(cell)[7:-9]
    color = str(cell)[-3:-1]
    if color == '22':
        filenames['RED'].append(filename)
        n+=1
    elif color == '23':
        filenames['GREEN'].append(filename)
        n+=1
