message when I did not have the readline() statement.
The example doesn't have any readline(). Make sure you open the file in
binary format ('wb' or 'rb').
If you have a list of objects: just write the list. It takes a single call
to pickle.dump(), and later, a single call to picle.load()
If you have too many objects and don't want to save/load all of them at
once, write them one at a time using pickle.dump(element, output_file,
-1), ending with a sentinel value (e.g. None): pickle.dump(None, ...)
You may read them again using something like this:
pfile = open(..., 'rb')
while True:
element = pickle.load(pfile)
if element is None: break
do_something_with(element)
pfile.close()
Ensure that you can save and load your data using a simple script,
*before* writing the GUI.
