I am having a dat file which contains data of the form:
0.23548 0.34938 0.54311 0.20902 0.52414 0.323418 1
for each observation and separated by each line. How would one convert this into an array with the first 6 variables as X's and the last variable as Y?
Thank you again!
The question is a bit unclear, but I'll try to answer anyway.
If the input file has the following structure (without the 1st and 3rd line):
X1 X2 X3 X4 X5 X6 Y(1-6) 0.23548 0.34938 0.54311 0.20902 0.52414 0.323418 1 X7 X8 X9 X10 X11 X12 Y(7-12) 0.23548 0.34938 0.54311 0.20902 0.52414 0.323418 1
then the following code should work. It returns a list of tuples (Xn,Yn).
points =  for line in open("file.dat", "r").readlines(): fields = map(float, line.split()) xs, y = fields[:-1], fields[-1] for x in xs: points.append( (x,y) ) print points
