A file having number of rows and columns where the input file are not fixed. Also, there can be duplicate valid points. The format of the input file looks like the following:
Point Sample1_X_Coordinate Sample1_Y_Coordinate Sample2_X_Coordinate Sample2_Y_Coordinate and so on
A 20 10 18 9
B 16 13 15 13
A 21 11 19 9
C 8 5 8 4
want to store these files like the following for doing additional manipulations (adding pseudocode )
outputdata[this_sample][this_point].append((this_sample_point_X_coordinate, this_sample_point_Y_coordinate))
i.e, the data to be stored in the following way:
outputdata[Sample1][A] = list[(20,10), (21,11)]
outputdata[Sample2][A] = list[(18,9), (19,9)]
How to implement the above in python?
Thanks!

with open(filename, 'rb') as csvfile:
for row in csv.reader(csvfile, delimiter='|'):
key, value = row[:2]
lstdct[key].append(value)
