Executing Python scripts with Conky.

Hey Folks, hope this isn't too simple where its slapping me in the face.

So I've created a weather script in python a few months ago and decided to throw it into my conky config. The problem is, conky won't output any of it. It has to be the script because I've tried making just a script that simply prints "hi"

#!/usr/bin/python
# hehe.py
print( "hi" )

And that works just fine. When I try my weather script, it just outputs a blank line as if nothing were there. The weather script works, I've executed it in my terminal just fine. I've set the mode to executable and everything. What am I doing wrong?

Here's the script (Don't make fun of it, now):

#!/usr/bin/python2
# coding: utf-8
# weather.py
# Coded on 09.25.09

import httplib, re, sys, os

rs = '######################'
ind = '\n# '
if len(sys.argv) !=1:
   city = sys.argv[1:]
   place = ""
   for e in city:
      if (place == ""):
         place = e
      else:
         place = place + '+' + e
else:
   print('Please enter a Zip/Area code or city name.')
   sys.exit()

def GrabHTML(place):
   '''Grab HTML'''
   try:
      url = '/' + place
      web = httplib.HTTPConnection('www.weatherreports.com')
      web.request("GET", url)
      ra = web.getresponse()
      html = ra.read()
      return html
   except:
      return '[!] Connection Error!'

def GetWeather(html):
   '''Grab Basic Weather Info.''' 
   try:
      if re.search('We have more than one location for your search.<br>', html):
         return '[!] Please be more specific in your location.'
      else:
         r = re.split(r'<span class="currentValue">(.+?)</span>', html)[1] # Time
         s = re.split(r'<div class="currentTemperature">(.+?)</div>', html)[1]
         x = re.split(r'Wind Spd:</span><span class="currentValue">(.+?)</span>', html)[1]
         g = re.split(r'Wind Dir:</span><span class="currentValue">(.+?)</span>', html)[1]
         p = re.split(r'Pressure:</span><span class="currentValue">(.+?)</span>', html)[1]
         t = re.split(r'Dewpoint:</span><span class="currentValue">(.+?)</span>', html)[1]
         y = re.split(r'Feels Like:</span><span class="currentValue">(.+?)</span>', html)[1]
         v = re.split(r'Visibility:</span><span class="currentValue">(.+?)</span>', html)[1]
         if re.search('&deg;', html):
            s = s.replace('&deg;', 'Â°')
            g = g.replace('&deg;', 'Â°')
            t = t.replace('&deg;', 'Â°')
            y = y.replace('&deg;', 'Â°')
         temp = '# Updated: ' + r + ind + 'Temp: ' + s + ind + 'Wind Spd: ' + x + ind + 'Wind Dir: ' + g + ind + 'Pressure: ' + p + ind + 'Dewpoint: ' + t + ind + 'Feels Like: ' + y + ind + 'Visibility: ' + v 
         return rs + '\n' + temp + '\n' + rs
   except:
      return '[!] Please use a real location.'

def Location(html):
   e = re.split(r'<title>Weather Report and Weather Forecast for (.+?)</title>', html)[1]
   return '# Weather for...' + ind + e

def Logo():
   print rs
   print '# Google.the.Kid Productions'
   return '# googlethekid[at]null[dot]net'   

html = GrabHTML(place)
print
print(Logo())
#print(Location(html))
print(GetWeather(html))
print '\n'

(Keep in mind some of the stuff in the piece is just for the output looks.)

The problem, I think, is that you have set the environment to python2 in the weather.py script. but you are calling python in conky -- which points to python3 in Arch.

If your script works with python3, simply change the environment in the script OR if it doesn't then in conky call it using python2

Sort of off-topic:
That weather script is somewhat nasty. if you know python I would suggest reawriting it using lxml or similar for sane parsing while you are at it. (and prefably, get some plain xml forcasts instead of parsing a html page)

Also, the try: except: block can actually cause problems since it will catch any errors, which would at worst case end up blocking.

It worked! Well, sort of. I did see it flash on conky a couple times but disappear quickly. So it's trying to work, perhaps it's the script?

Yeah, I know it's a bit rough. I'm sorta new to python so cleaning up is needed. Thanks for the tips. So like use Google's? I think they have an XML forecast.
Seeing as how it does run without errors I'll try removing those and see if that works. Thanks!
