Just a simple python weather script.
Sometimes we need simple solutions. An example is displaying data on a computer screen using conky. under Linux.
Another example is the display of data without using the browser.
Whether you use Windows or Linux python scripts come to help. Here's a simple example written in python that can display weather data.

import urllib
from xml.dom import minidom
wurl = 'http://xml.weather.yahoo.com/forecastrss?p=%s'
wser = 'http://xml.weather.yahoo.com/ns/rss/1.0'
def weather_for_zip(zip_code):
url = wurl % zip_code +'&u=c'
dom = minidom.parse(urllib.urlopen(url))
forecasts = []
for node in dom.getElementsByTagNameNS(wser, 'forecast'):
forecasts.append({
'date': node.getAttribute('date'),
'low': node.getAttribute('low'),
'high': node.getAttribute('high'),
'condition': node.getAttribute('text')
})
ycondition = dom.getElementsByTagNameNS(wser, 'condition')[0]
return {
'current_condition': ycondition.getAttribute('text'),
'current_temp': ycondition.getAttribute('temp'),
'forecasts': forecasts ,
'title': dom.getElementsByTagName('title')[0].firstChild.data
}
def main():
a=weather_for_zip("ROXX0003")
print '=================================='
print '|',a['title'],'|'
print '=================================='
print '|current condition=',a['current_condition']
print '|current temp =',a['current_temp']
print '=================================='
print '| today =',a['forecasts'][0]['date']
print '| hight =',a['forecasts'][0]['high']
print '| low =',a['forecasts'][0]['low']
print '| condition =',a['forecasts'][0]['condition']
print '=================================='
print '| tomorrow =',a['forecasts'][1]['date']
print '| hight =',a['forecasts'][1]['high']
print '| low =',a['forecasts'][1]['low']
print '| condition =',a['forecasts'][1]['condition']
print '=================================='
main()
Here is the result of script execution:
>>>
==================================
| Yahoo! Weather - Bucharest, RO |
==================================
|current condition= Light Snow
|current temp = -3
==================================
| today = 23 Feb 2011
| hight = 0
| low = -5
| condition = Light Snow
==================================
| tomorrow = 24 Feb 2011
| hight = 0
| low = -4
| condition = Mostly Cloudy

This is the code source:
I use two functions , first read url and secondary extract data.
This is the code source:
from xml.dom import minidom as dom
import urllib
def fetchPage(url):
a = urllib.urlopen(url)
return ''.join(a.readlines())
def extract(page):
a = dom.parseString(page)
item2 = a.getElementsByTagName('SendingDate')[0].firstChild.wholeText
print "DATA ",item2
item = a.getElementsByTagName('Cube')
for i in item:
if i.hasChildNodes() == True:
e = i.getElementsByTagName('Rate')[10].firstChild.wholeText
d = i.getElementsByTagName('Rate')[26].firstChild.wholeText
print "EURO ",e
print "DOLAR ",d
if __name__=='__main__':
page = fetchPage("http://www.bnro.ro/nbrfxrates.xml")
extract(page)
Result is :
DATA 2011-02-03
EURO 4.2609
DOLAR 3.0921
