Weather app using Django | Python

In this tutorial, we will learn how to create a Weather app that uses Django as backend. Django provides a Python Web framework based web framework that allows rapid development and clean, pragmatic design.

Basic Setup –
Change directory to weather –

cd weather

Start the server –

python manage.py runserver

To check whether the server is running or not go to a web browser and enter http://127.0.0.1:8000/ as URL. Now, you can stop the server by pressing

ctrl-c

Implementation :

 python manage.py startapp main

Goto main/ folder by doing :

cd main 

and create a folder with index.html file: templates/main/index.html

Open the project folder using a text editor. The directory structure should look like this :

Now add main app in settings.py

Edit urls.py file in weather :

from django.contribimport admin from django.urlsimport path, include       urlpatterns= [     path('admin/', admin.site.urls),     path('', include('main.urls')), ]

edit urls.py file in main :

from django.urlsimport path from .import views    urlpatterns= [          path('', views.index), ]

edit views.py in main :

from django.shortcutsimport render # import json to load json data to python dictionary import json # urllib.request to make a request to api import urllib.request       def index(request):     if request.method== 'POST':         city= request.POST['city']         ''' api key might be expired use your own api_key             place api_key in place of appid ="your_api_key_here "  '''            # source contain JSON data from API            source= urllib.request.urlopen(             'http://api.openweathermap.org/data/2.5/weather?q ='                      + city+ '&appid = your_api_key_here').read()            # converting JSON data to a dictionary         list_of_data= json.loads(source)            # data for variable list_of_data         data= {             "country_code":str(list_of_data['sys']['country']),             "coordinate":str(list_of_data['coord']['lon'])+ ' '                         + str(list_of_data['coord']['lat']),             "temp":str(list_of_data['main']['temp'])+ 'k',             "pressure":str(list_of_data['main']['pressure']),             "humidity":str(list_of_data['main']['humidity']),         }         print(data)     else:         data={}     return render(request,"main/index.html", data)

You can get your own API key from : Weather API

Navigate to templates/main/index.html and edit it: link to index.html file

Make migrations and migrate it:

python manage.py makemigrations
python manage.py migrate

now let’s run the server to see your weather app.

python manage.py runserver
