appending a file

[Lenny Self]

Hello.

I am a little frustrated. After looking all over the place ( Learning
Python, the Python Pocket Reference, Library Reference) I have been unable
to find how to append to the end of an existing text file using python in
any way other than reading the entire contents of the file out to a list,
adding the additional information, and then writing it all back to the
original file.  I know there must  be a better way to do this; for the life
of me, however, I seem to me unable to find it.

Can anyone help me out?
