New to Python: my impression v. Perl/Ruby
Very interesting. I too am deciding between the three languages. I find Python to be the easiest to use. By far. I find the forced indentation in Python a blessing in disguise. It seems Python is making in-roads into the progarmming community. With Ruby, its back to idiosyncratic and abstract syntax. Why? Is it necessary to be cryptic? Whoever can figure out the puzzle is the smartest one? "Everything should be made as simple as possible, but no simpler." Albert Einstein Thanks for sharing your thoughts!

Spanish Accents
Hi; If I write a python page to print to the web with Spanish accents all is well. However, if I read the data from a text file it prints diamonds with question marks wherever there are accented vowels. Please advise. TIA, Stan -- http://mail.python.org/mailman/listinfo/python-list

So I tried this:
file = open(p + "2.txt")
for line in file:
print unicode(line, 'utf-8')
and got this error:

I'm baffled. I duplicated your print statements but when I run this code
(or any of the 3 encodings):
file = codecs.open(p + "2.txt", "r", "cp1252")
#file = codecs.open(p + "2.txt", "r", "utf-8")
for line in file:
print line
I get this error:

Python with Eclipse
I've been trying to use Eclipse with Python on Linux for a while and have noticed something odd. After running the code or debugging a few times, its responsiveness gets really bad. Upon checking the equivalent of the task manager, I find several instances of Python running. When I kill these instances, the responsiveness comes back. I'm not sure if there is a better place to post this, but it is Python related. Is this just an issue with Eclipse or is there something else I should inspect? Any help would be appreciated.
