Newbie: EOF Error when making arrays .fromfile

[Matt Strange]

hello all, i am very new to python and i'm using v2.2 on a Win98SE
machine.  i needed to read in double-type data from an ASCII file
(http://dnijaguar.tripod.com/planet0.dat).  this file contains 3000
doubles separated by the tab("\t") value.  after reading information
posted on this newsgroup, i decided that it would be best to first
translate this ASCII data into a binary file using a c++ program
(http://dnijaguar.tripod.com/atb.cpp).  then, i could read in this
binary file (http://dnijaguar.tripod.com/bin0.dat) with the following
lines of python:

>>> coord = array('d')
>>> coord.fromfile(open("bin0.dat",'r'),3000)

however, there is a problem.  i recieve the error:
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
EOFError: not enough items in file

and when i type in "coord" from the >>> prompt to see what is stored
inside it, i see the values listed at the very end of this message;
i.e. the correct values, but definately not 3000 of them like i
wanted.  i would appreciate it if someone would tell me the reason i
am having this problem and the code necessary to fix it (with ASCII or
binary files). thank you very much for your help.

value of coord shown on command line:
