LOADING DATA INTO ARRAYS

[satish k.chimakurthi]

Hi,

     I am trying to collect the following data in X,Y,Z arrays as following:
    
  1.00000000000000        0.00000000000000D+000   0.00000000000000D+000
  0.932113519778473       0.362166241174114        0.00000000000000D+000
  0.737671227507627       0.675160099611485        0.00000000000000D+000

   8.83176797852179D-002  0.996092358889152        0.00000000000000D+000

After loading them into X,Y,Z arrays, I should be in a position to access the 
first line as X[0],Y[0], Z[0] and second line stuff as X[1],Y[1],Z[1].

I have written the following code which is not working for some reason.  Can 
anyone suggest any changes:

ifile1 = open('fluidcylinder', 'r')  #fluidcylinder contains the above data
for line in ifile1:
     xval,yval=string.split(line)
     x.append(xval)
     y.append(yval)

The error I am getting after the compilation is as follows:

 xval,yval=string.split(line)
ValueError: unpack list of wrong size


I would really appreciate if someone can help me with this.

Thanks in advance,

SATISH
