Hi Dev,
In this article we will cover on how to implement if statement in django python template example. I would like to share with you how to use if/else condition on python django templates?. let’s discuss about using if else condition in python django template. I explained simply about nested if else in django template. Let's get started with if else tag in django template example.
So, in this example we can check the two numbers is greater than first number and in second example check the odd and even number.
Here i explained simply step by step example of how to generate qr code in django python.
Example : 1In this step, we need to create the views for performing the get number.Open the core/views.py file and add:
core/views.py
from django.shortcuts import render
def index(request):
number1 = int(request.GET.get('number1', 0))
number2 = int(request.GET.get('number2', 0))
dict={
'number1' : number1,
'number2' : number2
}
return render(request, 'index.html', dict)
Next, open the core/templates/index.html file and the add:
<!DOCTYPE html>

Step 7 : Creating URLs
In this section, we’ll create the urls to access our core views.Go to the urls.py core/urls.py file and update it as follows:
core/urls.py
from django.urls import path
from . import views
urlpatterns = [
path('', views.index),
path('odd-even/', views.oddEven),
]
Next, we will require the modify the urls.py your root preoject folder lets update the file.
example/urls.py
from django.contrib import admin
from django.urls import path, include
urlpatterns = [
path('admin/', admin.site.urls),
path('', include('core.urls')),
]
Run the Server
In this step, we’ll run the local development server for playing with our app without deploying it to the web.
python manage.py runserver
Next, go to the http://localhost:8000/ address with a web browser.
I Hope It will help you....
