Graceful detection of EOF

[MickeyBob]

How does one detect the EOF gracefully? Assuming I have a pickle file
containing an unknown number of objects, how can I read (i.e.,
pickle.load()) until the EOF is encountered without generating an EOF
exception?

Thanks for any assistance.

Of course it is not difficult to test if you are reading the first line
or another one, but it hurts my feelings to do a test which by definition
succeeds at the first record, and never afterwards.
Any suggestions ?

An alternative approach (which I'm sure will offend just as many
sensibilities) is to use a function that replaces itself.

------ Pseudo-code ------
def process_firstli ne(...):

# ...do something here...
global processline
processline = process_otherli nes
def process_otherli nes(...):

# ...do something here...
processline = process_firstli ne

for line in file:
result = processline(lin e)

----------------------------

If you read more than one file you'll need to reset processline at the
beginning of each file.

I never said this was a *good* way, just one way. :-)
