Learning Python
I had set myself a goal to make around 20 blog posts per year, it’s now almost December and I still have not bothered. It is safe to say I am not exactly prolific.
I decided that I would learn python, surprisingly it’s been really easy to pick up and I thought I would share some of the things I made in my first 2 days of python.
The first I written was to phrase the results from yahoo’s football score page(http://uk.eurosport.yahoo.com/football/premier-league/2011-2012/results/2011_08.html). I was on this page anyway and thought why not!
#!/usr/bin/python
import urllib2
import re
response = urllib2.urlopen('http://uk.eurosport.yahoo.com/football/premier-league/2011-2012/results/2011_08.html')
html = response.read()
re_channel = re.compile("<td class=\"ko\"><abbr class=\"dtstart\" title=\"\">([0-9a-zA-z ,:]*)</abbr></td>" +
"\n <td class=\"match.*?\n" +
" <a href=.*?\">" +
"\n <span class=\"home\">([a-zA-Z ]*)</span>.*?" +
"\n <span class=\"score\">([0-9 :-]*)</span>.*?" +
"\n <span class=\"away\">([a-zA-Z ]*)</span>", re.I | re.S | re.M)
find_result = re_channel.findall(html)
print find_result
Sample output
[('13 Aug, 15:00', 'Wigan Athletic', '1 - 1', 'Norwich City'), ('13 Aug, 15:00', 'Fulham', '0 - 0', 'Aston Villa'), ('13 Aug, 15:00', 'Blackburn Rovers', '1 - 2', 'Wolverhampton Wanderers'), ('13 Aug, 15:00', 'Liverpool', '1 - 1', 'Sunderland'), ('13 Aug, 15:00', 'Queens Park Rangers', '0 - 4', 'Bolton Wanderers'), ('13 Aug, 17:30', 'Newcastle United', '0 - 0', 'Arsenal'), ('14 Aug, 13:30', 'Stoke City', '0 - 0', 'Chelsea'), ('14 Aug, 16:00', 'West Bromwich Albion', '1 - 2', 'Manchester United'), ('15 Aug, 20:00', 'Manchester City', '4 - 0', 'Swansea City'), ('20 Aug, 12:00', 'Sunderland', '0 - 1', 'Newcastle United'), ('20 Aug, 12:45', 'Arsenal', '0 - 2', 'Liverpool'), ('20 Aug, 15:00', 'Swansea City', '0 - 0', 'Wigan Athletic'), ('20 Aug, 15:00', 'Aston Villa', '3 - 1', 'Blackburn Rovers'), ('20 Aug, 15:00', 'Everton', '0 - 1', 'Queens Park Rangers'), ('20 Aug, 17:30', 'Chelsea', '2 - 1', 'West Bromwich Albion'), ('21 Aug, 13:30', 'Norwich City', '1 - 1', 'Stoke City'), ('21 Aug, 14:05', 'Wolverhampton Wanderers', '2 - 0', 'Fulham'), ('21 Aug, 16:00', 'Bolton Wanderers', '2 - 3', 'Manchester City'), ('22 Aug, 20:00', 'Manchester United', '3 - 0', 'Tottenham Hotspur'), ('27 Aug, 12:05', 'Aston Villa', '0 - 0', 'Wolverhampton Wanderers'), ('27 Aug, 12:30', 'Wigan Athletic', '2 - 0', 'Queens Park Rangers'), ('27 Aug, 15:00', 'Swansea City', '0 - 0', 'Sunderland'), ('27 Aug, 15:00', 'Chelsea', '3 - 1', 'Norwich City'), ('27 Aug, 15:00', 'Blackburn Rovers', '0 - 1', 'Everton'), ('27 Aug, 17:30', 'Liverpool', '3 - 1', 'Bolton Wanderers'), ('28 Aug, 13:00', 'Newcastle United', '2 - 1', 'Fulham'), ('28 Aug, 13:30', 'Tottenham Hotspur', '1 - 5', 'Manchester City'), ('28 Aug, 15:00', 'West Bromwich Albion', '0 - 1', 'Stoke City'), ('28 Aug, 16:00', 'Manchester United', '8 - 2', 'Arsenal')]
The next was to obtain a list of the uk charts top 100 and find the youtube video for it.

Then I wanted to test threading so I came up with something to check a list of links and obtain the "Server:" header
#!/usr/bin/env python
import urllib2
import re
import os
import sys
import time
from multiprocessing import Pool
#Accept file name as input or use default
try:
filename = sys.argv[1]
except IndexError:
filename = "links"
#Function to load urls from file
def loadurls(filename):
try:
inputdata = file(filename).readlines()
if len(inputdata) > 0:
return inputdata
except:
print "ERROR - Unable to process url list"
sys.exit()
#Function to get SERVER header
def getversion(url):
try:
request=urllib2.Request(url)
response=urllib2.urlopen(request)
version=response.info().getheader('Server')
except:
return "ERROR - Unable to fetch %s" % (url)
if version: print "Url: %s Version: %s" % (url, version)
start = time.time()
urls=loadurls(filename)
p = Pool(15)
data = p.map(getversion,urls)
elapsed = (time.time() - start)
print "Processed %s urls in %0.2f seconds" % (len(urls), elapsed)
Sample output
scott@scott:~/python$ ./server-header.py list Url: http://www.bbc.co.uk Version: Apache Url: http://www.google.co.uk Version: gws Url: http://www.scottmcintyre.net Version: Apache Processed 4 urls in 1.07 seconds
None of these really serve any purpose and were merely tests I thought I would share. Overall things have been quite easy and feel reasonably confident after just 2 days.
