I'm sorry you didn't get to read my next message because in there I
said that you yourself had already solved my problem a few weeks ago.

I am working with texts that are encoded as ISO-8859-1. I have
included the following two lines at the beginning of my python script:
!/usr/bin/env python
# -*- coding: iso-8859-1 -*-
If I'm not mistaken, this should tell Python that accented characters
such as 'á', 'Á', 'ö' or 'è' should be cons

Mmm. No, I didn't consider it because I didn't even know such a method
existed. This can turn out to be very handy but I don't think it would

I'm trying to use regular expressions to extract strings that match
certain patterns in a collection of texts. Basically these texts are
edited versions of medieval manuscripts that use certain symbols to
mark information that is useful for filologists.
I'm interested in isolating words that have

the dictionary. Thanks a lot again.

OK, I see. Now that I managed to build the dictionary, I did a print to
confirm that indeed the dictionary was created and it had the intended
contents and I was surprised to see that the order of the items in it was
totally changed. So the text file from which the dictionar

That is, now I do get a list but as you can see I get the newline character

As you see, I am very green. My embarrassment at realizing how basic my

don't do it, I will never learn.

Hi,
This is my first posting to this list. Perhaps this has a very easy answer
but before deciding to post this message I consulted a bunch of Python
manuals and on-line reference documents to no avail. I would be very
grateful if someone could lend me a hand with this.
