let's see bellow example here you will learn python django filter less than example.

Django Admin Interface:

In this example how to use the “less than” operator with the help of an example. we are going to select all the database objects whose age is less than 22. The code for the example is as follows.

from django.http import HttpResponse
from base.models import Student

def index(request):
    queryset = Student.objects.filter(age__lt=22).values()
    print(queryset)

    return HttpResponse(queryset)

[
    {
        'id': 2, 
        'name': 'Nikhil', 
        'age': 20
    },
    {
        'id': 5, 
        'name': 'Vishal', 
        'age': 19
    }
]

from django.http import HttpResponse
from base.models import Student

def index(request):
    queryset = Student.objects.filter(age__lte=22).values()
    print(queryset)

    return HttpResponse(queryset)

[
    {
        'id': 2, 
        'name': 'Nikhil', 
        'age': 20
    }, 
    {
        'id': 3, 
        'name': 'Keval', 
        'age': 22
    }, 
    {
        'id': 5, 
        'name': 'Vishal', 
        'age': 19
    }
]
