If you don't want to go with COM, there are a couple of packages that might be
useful: xlrd and pyExcelerator.
I've used pyExcelerator; it includes functions to parse a spreadsheet into a
dictionary. You could do something like this (untested):
workBook = pyExcelerator.parse_xls('myfile.xls')
sheet = workBook['Sheet1'] # Or whatever the worksheet is called
# prints something like: ((3, 2), 'foo'), ((1, 0), 'bar'), etc
rowsAbove3 = dict([(x, sheet[x]) for x in sheet if x > 3])
