i working data "water falled" (in excel) becomes normal after number of lines in excel. essentially need script remove empty data rows , keep full rows, location of rows data full variable, , not experienced python not quite sure how filter out "waterfall" rows. i attached simple example of mean, row 10 script need start keeping rows: excel example what have written, assuming .py script in same folder data needs filtered, along folder 'archive' , 'downsampled'. folders = os.listdir('./') folder in folders: filename = folder f = open(filename,'r') lines = f.readlines() f.close() shutil.move(folder, './archive') f_out = open('./downsampled/' + folder + '.csv', 'w') #filter data. f_out.close() i ended using pandas dropna() feature. thank you.

i trying implement calculated member (ssrs or ssas ) show me average values per customer, need divide sum of values projects, , divide amount of projects don't have 0 value. a similar table of values 1 using shown below.   > customer | project | value | > customer1 | project1 | 124.24... | > customer1 | project2 | 0.00 | > customer1 | project3 | 242.221... | > customer1 | project3 | 72.221... |   tried in calculated member following (i tried in both ssrs , ssas) sum([measures].[value]) /count(filter([order].[project], [measures].[value] > 0)) my hope filter out amount of projects have value of zero, , divide sum of values amount of projects have value of <> 0. the problem is, when browser so i try calculated member out count value of projects (relative ex. above) 1 instead of 3, , average value : (124.24 + 0 + 242.221 + 72.221) / 1 as opposed (124.24 + 0 + 242.221 + 72.221) / 3  (not devide 4 beca...
