Reference list of Xamarin Android.Graphics.Color's

Could not find reference list for the colors defined in the Android.Graphics.Color' static properties,
so decided to look them up with reflection, and put them here for my own reference, probably not the
smartest way to do it, but here's the list anyway:


Wondering if the list of predefined colors in Android.Graphics.Color' static properties is same as System.Drawing.Colors in windows, the list looked the same.

Simple python html parsing and list comprehension

Was just watching call-in television-show, where they asked people to find finish country names that are 5 letters long and end up in a-letter.

So decided to test how to do that fast way with python.

First just fetch wiki page about country names:

import urllib2;
response = urllib2.urlopen('https://fi.wikipedia.org/wiki/Luettelo_itsen%C3%A4isist%C3%A4_valtioista')

content = response.read()

Parse the content:

import BeautifulSoup as bs
soup = bs.BeautifulSoup(content)

Get all links in the page:

links = soup.findAll('a')

Get link texts that have ref starting with "/wiki":

wikisT = [l.getText() for l in links if l.get('href')!=None and l.get('href').startswith('/wiki')]

Get links that have text with length of 5 and end up in letter a:

wikisT5A = [w for w in wikisT if len(w)==5 and w[-1]=='a']

Print out wikisT5A in my iPython console:



Writing this blog entry took longer than finding out the countries with python, less than 5 mins or so (and that included googling about how urllib2 is used, have used it before, but didn't remember). Yep I like python these days.
