Maybe RTFM, and then wrap the .fromfile() call with an appropriate 
exception handler:

'''
fromfile(f, n)
     Read n items (as machine values) from the file object f and append 
them to the end of the array.

If less than n items are available, EOFError is raised, but the items 
that were available are still inserted into the array.
'''

Note the last sentence above.
