eof?

[Cris A. Fugate]

Can't find a convenient way to check for the end of an input file.
I would like to say something like this where fh.eof would return
a boolean value for the eof condition. How is this done, or is
there another way? TIA

fh = open("file", "r")
while (not fh.eof):
   fh.readline()
