My first python script, using pandoc to convert a webpage to markdown
# pandoc-webpage.py
# Requires: pyandoc http://pypi.python.org/pypi/pyandoc/
# (Change path to pandoc binary in core.py before installing package)
# TODO: Iterate over a list of webpages
# TODO: Clean up HTML by removing hard linebreaks
# TODO: Delete header and footer
import urllib2
import pandoc
# Open the desired webpage
url = 'http://mcdaniel.blogs.rice.edu/?p=158'
response = urllib2.urlopen(url)
webContent = response.read()
# Call on pandoc to convert webContent to markdown and write to file
doc = pandoc.Document()
doc.html = webContent
webConverted = doc.markdown
f = open('wendell-phillips.txt','w')
f.write(webConverted)
f.close()

here you go:

start = webContent.find('<title>')+7
end = webContent.find('</title>')
rawTitle = webContent[start:end]

Then, you probably want to clean that title up:

rawTitle = rawTitle.replace('Offprints  &raquo; Blog Archive   &raquo; ','')
if rawTitle.find('&#8220;'):
    rawTitle = rawTitle.replace('&#8220;','')
    rawTitle = rawTitle.replace('&#8221;','')
title = rawTitle.replace(' ','_')

The replace method is a built-in string method that let's you, well, replace parts of a string. But, strings are immutable, so you have to re-assign the new string to your variable each time you use it to "save" the change. This little bit then gets rid of un-necessary parts of your html title, and the codes for typographic quote marks, and replaces the remaining spaces with underscores to your new file will be named: blog_post_title.txt

Then, you'd use this to name the new file:

f = open(title+'.txt', 'w').write(webConverted)

Also, in the interest of a little more brevity, you could make a few little changes to the code you have:

import urllib2, pandoc

url = 'http://mcdaniel.blogs.rice.edu/?p=158'
response = urllib2.urlopen(url).read()

# The first line creates a pandoc object. The second assigns the html response to that object
doc = pandoc.Document()
doc.html = response

f = open('wendell-phillips.txt','w').write(doc.markdown)

This way, the file is also automatically closed. That gives you six lines of code instead of eleven!
