save some information from a xml or json to a txt file

LukeCodewalker

@gismo2006 here it is. just place your app id and the path of the file, where the text should go.

import json
import subprocess

APP_ID = ''
FILE_PATH = 'test.txt'

url = 'http://api.openweathermap.org/data/2.5/weather?id=2934486&lang=de&units=metric&mode=json&appid=' + APP_ID
curl_req = 'curl -L ' + '"' + url + '"'
p = subprocess.Popen(curl_req, stdout=subprocess.PIPE, shell=True)
(output, err) = p.communicate()  
p_status = p.wait()

try:
    decoded = json.loads(output)
    weather = decoded['weather'][0]['description']
    temp = decoded['main']['temp']
    f = open(FILE_PATH,'w')
    f.write('Today is ' + weather + ' and ' + str(temp) + ' degrees.')
    f.close()
except (ValueError, KeyError, TypeError):
    pass

Hi, thank you for the code. But there was a little misstake I think. I have copied your code and save. put in my api and the right folder.

then the first try. All works fine the code generate a test.txt file. But then I oen the txt file it was empty.
Ok I think maybe I put in something wrong. But everything was ok.

At a second try I chnage the folder name, because I think maybe the was some folder Rights or something else. But the same. The txt file was empty.

At my next try I cut of the f.write line and there was only written f.write(‘Today is’)
And I see everything work like it should. In the txt file was written Today is. Now I put some more in this line again. Everything works fine till I put the word weather. If I put this the txt file will be empty.

I like to try something mor later today. But I want give you a feedback. And I like to say thank you.

Sorry I forgett there was no error. Also Python displays no error if I try it a the Python IDLE.

@gismo2006 I think I got the problem. The german description can contain letters like äöü etc. i will fix that later when i’m at home.

Now it should work

#!/usr/bin/python
# -*- coding: utf-8 -*-
import codecs
import json
import subprocess

APP_ID = ''
FILE_PATH = 'test.txt'

url = 'http://api.openweathermap.org/data/2.5/weather?id=2934486&lang=de&units=metric&mode=json&appid=' + APP_ID
curl_req = 'curl -L ' + '"' + url + '"'
p = subprocess.Popen(curl_req, stdout=subprocess.PIPE, shell=True)
(output, err) = p.communicate()  
p_status = p.wait()

try:
    decoded = json.loads(output)
    weather = decoded['weather'][0]['description']
    temp = decoded['main']['temp']
    f = codecs.open(FILE_PATH,'w', 'utf-8')
    f.write('Today is ' + weather + ' and ' + str(temp) + ' degrees.')
    f.close()
except (ValueError, KeyError, TypeError):
    pass

i did some reverse engineering of the dwd-website and found this json file.
i had a short look at your link and did not found something similar there. do you know if theres an app for ios where the data is shown? maybe i can help you then.
