Weather in SVG

[apples723]

ok so i wrote another weather application this time it displays the weahter as a gui my only problem is when i want to change the location you have to change the lattitude and longitude manually i have tried using a module to convert it using the city location but when every i use any varabiles in the link it fails to pick it up take a look at my current code ill have some notes in it to see if you can help me

Code: Select all

import time
import urllib2, time
from xml.dom import minidom
import datetime
import codecs
import webbrowser
import easygui as eg
import Tkinter

#title = "Start"
#msg = "Touch Ok to begin"
#eg.msgbox(msg, title)
weather_xml = urllib2.urlopen('http://graphical.weather.gov/xml/SOAP_server/ndfdSOAPclientByDay.php?whichClient=NDFDgenByDay&lat=42.0228&lon=-93.4522&format=24+hourly&numDays=4&Unit=e').read() #if i try and define the lat and lon with string formating it wil fail i dont know why 
dom = minidom.parseString(weather_xml)


xml_temperatures = dom.getElementsByTagName('temperature')
highs = [None]*4
lows = [None]*4
for item in xml_temperatures:
    if item.getAttribute('type') == 'maximum':
        values = item.getElementsByTagName('value')
        for i in range(len(values)):
            highs[i] = int(values[i].firstChild.nodeValue)
    if item.getAttribute('type') == 'minimum':
        values = item.getElementsByTagName('value')
        for i in range(len(values)):
            lows[i] = int(values[i].firstChild.nodeValue)

xml_icons = dom.getElementsByTagName('icon-link')
icons = [None]*4
for i in range(len(xml_icons)):
    icons[i] = xml_icons[i].firstChild.nodeValue.split('/')[-1].split('.')[0].rstrip('0123456789')

Hi,

What error were you getting, and what values were you trying to insert. Thanks.

[DrMag]

Agreed; more information on the errors you're encountering would be helpful. For example-- you mention that putting the lat/long in by string formatting isn't working. Where is it failing? Does the formatting itself fail, or does it format to a string that fails when you try to pull the results?

I'd expect the latter, in which case something like

Code: Select all

weather_xml=urllib2.urlopen('...&lat={0:.4f}&lon={1:.4f}...'.format(latitude,longitude))

is probably what you're looking for. Just plugging in the float values would insert more decimal places than the xml script may be looking for. But I'm just guessing at the problem here... some description of your actual error results would be helpful.
