Hi
Welcome to python !
there a a few suggestions in ur code which is a good practice to follow.
In the snippet:

> > for x in range(len(x_value)):
> >              x_co = float(x_value[x])-float(x_value[x+1])
> >              y_co = float(y_value[x])-float(y_value[x+1])
> >              z_co = float(z_value[x])-float(z_value[x+1])
> >              data = math.sqrt(x_co)*(x_co)+(y_co)*(y_co)+(z_co)*(z_co)
> >              print data

U suddenly change the indent from four spaces which u followed in previous
for loop. pls maintain consistency in indent. Standard  convention is to use
four spaces for indent.

Another problem is that u have not closed the filehandle  in the program!
