[Tutor] Python Challenge
Greetings: Here's a fun site, though probably geared more for intermediate Python programmers, than for beginners: http://www.pythonchallenge.com/ It's 33 levels of riddles that can be solved with Python in some way or another. =) So you have the site up in your browser, and your Python interpreter up, and you try to solve each riddle to get to the next level. There isn't much mouse work involved... you can't *click* your way through it. You have to think of Python solutions to solve each riddle. Each riddle is a combination of a picture and a clue, or hint. Read the hint, and study the picture carefully to figure out what to do.

Hi All,
Been tasked with an assignment that is kicking my butt. We have been asked
to write a py utilizing cgi to ask for simplistic web form guestbook
information (name and email). I think I am lost on whether or not my actual
py script needs to link to a cgi script or if I can do it all in a py
script. It needs to log entries to a text file and everytime I think I have
it working I go to my text file and it remains empty. I don't know if I can
post my script code in here so if I can not then my apologies forthcoming.
Any help or advice is most appreciated.
py script:
#!c:\python25\python.exe
import cgi, cgitb, os
temp =
html
body
form action=sample.cgi
First Name: input type=text name=fnamebr
Last Name: input type=text name=lnamebr
Email: input type=text name=emailbr
hr
input type=submit
/form
/body/html
path = 'c:\\file'
# Create instance of FieldStorage
form = cgi.FieldStorage()
# Get data from field 'name'
fname = form.getvalue('fname')
# Get data from field 'address'
lname = form.getvalue('lname')
# Get data from field 'email'
email = form.getvalue('email')
if not os.path.isdir(path):
os.mkdir(path)
e=open(path + '\\' + 'logbook.txt','a')
e.write(%s#%s#%s\n % (fname,lname,email))
e.close()
print 'Done'
What am I doing wrong? Been working on this two weekends in a row and the
assignment is already late.
Thanks,
TheSarge

Re: [Tutor] more encoding confusion
Kent, Many thanks again, and thanks too to Paul at
http://tinyurl.com/yrl8cy.
That's very effective, thanks very much for the detailed explanation;
however, I'm a little surprised that it's necessary. I would have thought
that there would be some standard module that included a unicode
equivalent
of the builtin method isupper().

First you have to decode the file to a Unicode string.
Then build the set of matching characters and build a regex. For
example,
something like this:
data = open('data.txt').read().decode('utf-8').splitlines()
uppers = u''.join(unichr(i) for i in xrange(sys.maxunicode)
if unichr(i).isupper())
I modified uppers to include only the latin characters, and added the
apostrophe to catch placenames like L'ISLE.
upperRe = u'^[%s]{2,}' % uppers
for line in data:
if re.match(upperRe, line):

Hmm...actually, isupper() works fine on unicode strings:
In [18]: s='H\303\211RON'.decode('utf-8')
In [21]: print 'H\303\211RON'
HÉRON
In [22]: s.isupper()
Out[22]: True
:-)

Then you are back to needing a regular expression I think.

We welcome code. Without it we can't begin to help. Also if you get an
exception please post the traceback also.
Any help or advice is most appreciated.

I assume you included the form html as a comment, and that the actual
form is sent to the browser first, then the actual cgi program starts
with path =
The only problem I see is that the code to write the file is bypassed
when the path already exists. You should be able to fix that with some
changes to indentation.
Been working on this two weekends in a row and the
assignment is already late.
Next time ask sooner. We don't DO homework for students, but are glad to
help when we see your effort and specific problems.
It is good that you imported the cgitb module. Just add
cgitb.enable()
to activate it.

Your python script is a CGI script and it needs to run under a web
server.
There is a simple CGI server in the Python library that you can use
for
testing...
#!c:\python25\python.exe
import cgi, cgitb, os
temp =
html
body
form action=sample.cgi
First Name: input type=text name=fnamebr
Last Name: input type=text name=lnamebr
Email: input type=text name=emailbr
hr
input type=submit
/form
/body/html
path = 'c:\\file'
# Create instance of FieldStorage
form = cgi.FieldStorage()
# Get data from field 'name'
fname = form.getvalue('fname')
# Get data from field 'address'
lname = form.getvalue('lname')
The comments seem to be wrong, assuming the html
in temp ids the same as is in the html file that calls this?
# Get data from field 'email'
email = form.getvalue('email')
if not os.path.isdir(path):
os.mkdir(path)
e=open(path + '\\' + 'logbook.txt','a')
e.write(%s#%s#%s\n % (fname,lname,email))
e.close()
print 'Done'
Bob has already pointed out the bug here...

Ah! I'm finally starting to get it. My problem wasn't with a regex to test
the line, my problem was with reading the file in as utf-8 to begin with.
When I take your advice and decode() right from the start using:
open('textfile').read().decode('utf-8').splitlines()
instead of
input = open('textfile', 'r')
text = input.readlines()
Then the regex problem does not even arise. Now I can use this instead:
for line in data:
if line[0:2].isupper():
as you point out, isupper() works just fine on unicode strings; it also
seems to consider the apostrophe uppercase as well because this catches
not only HÉRON, but L'ISLE as well.
Now my only glitch is that line.title() screws up placenames like STOKE
(BISHOP'S), turning it into Stoke (Bishop'S).___
