Comparison Operators in Python

In this section, we’ll explore what a comparison operator is and the different kinds of comparison operators available in Python.

In Python, a comparison operator is also known as a relational operator. Comparison operators are used to compare the values of two operands and returns True or False depending on whether the condition is satisfied or not.

The comparison operators available in Python are listed below.

OperatorOperator NameDescription
==EqualityThe condition becomes true if the values of two operands are equal.
!=InequalityWhen the values of two operands differ, the condition is true.
>Greater thanIf the left operand’s value is greater than the right operand’s value, the condition is true.
>=Greater than or Equal toThe condition is true if the value of the left operand is larger than or equal to the value of the right operand.
<Less thanIf the left operand’s value is less than the right operand’s value, the condition is true.
<=Less than or Equal toThe condition is true if the value of the left operand is less than or equal to the value of the right operand.

How to compare two integers in python Django

It’s time to learn how to show Python program output on an HTML page using Django till now we’ve only known how to represent it in a console or terminal. So in this section, we will learn to compare two integers in python using Django.

There are two ways to compare two integers using Django:

  • Using Views
  • Using Template

Using Views: Views are Python functions or classes that receive and respond to web requests in the Django framework. A plain HTTP response, an HTML template response, or an HTTP redirect response that sends the user to another page can all be used as responses.

Using Template: Django templates use tags and filters to define a language that’s similar to Python—but isn’t Python. Tags are similar to the keywords and functions in the template language. Keywords and functions in Python offer control flow and the tools on which your code is constructed. Inheritance, conditional operation, looping, comments, and text handling are all provided by Django’s built-in tags.

Compare two integers in view

In this section, we’ll learn how to use Django’s view to compare two integers. Let’s, clarify our concepts by using various examples.

I’ll show you the project’s urls.py and app’s urls.py file before I start the demonstration. As it remains the same in all of the examples.

The PythonGuides urls.py file:

from django.contrib import admin
from django.urls import path, include

urlpatterns = [
    path('admin/', admin.site.urls),
    path('', include('home.urls'))
]

This means that when you open your project in the browser, it will take you to your home.urls.

Now, see the home urls.py file:

from django.urls import path, include
from home import views

urlpatterns = [
    path('', views.home, name='home')
]

It moves to the views.py file of the home app.

Example #1

In this example, we are using the equality operator to compare two integers.

The views.py file:

from django.http import HttpResponse

# Create your views here.

def home(request):
    x = 6
    y = 6
    if(x == y):
        html = "<html><body><b>Yes, X is equals to Y </b></body></html>"
        return HttpResponse(html)
    else:
        html = "<html><body><b>No, X is not equal to Y</b></body></html>"
        return HttpResponse(html)

We define two integers, x & y, and then use the equality operator to compare them. We render the output on the HTML page by using the if-else statement in Python.

Now, if we run the development server and move to the mapped URL, we will get the following output.

Equality Operator

Example #2

In this example, we are using the inequality operator to compare two integers.

The views.py file:

from django.shortcuts import render

# Create your views here.

def home(request):
    x = 10
    y = 12
    result = (x != y)
    return render(request, 'home.html', {'result':result})

We define two integers, x & y, and then use the inequality operator to compare them. We render the result on the HTML page.

The home.html page:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>PythonGuides</title>
</head>
<body>
    <p>
        <b> X is not equal to Y: </b>{{result}}
    </p>
</body
</html>

In the home.html file, we are just using the variable to get the result. In the end, we will get the following output.

Inequality Operator

Example #3

In this example, we are using the greater than operator to compare two integers.

The views.py file:

from django.shortcuts import render

# Create your views here.

def home(request):
    x = 10
    y = 12
    result = (x > y)
    return render(request, 'home.html', {'result':result})

We define two integers, x and y, and then use the greater than operator to compare them. We render the result on the HTML page.

The home.html page:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>PythonGuides</title>
</head>
<body>
    <p>
        <b> X is greater than Y: </b>{{result}}
    </p>
</body
</html>

In the home.html file, we are just using the variable to get the result. In the end, we will get the following output.

Greater Than Operator

Example #4

In this example, we are using the greater than or equal to an operator to compare two integers.

The views.py file:

from django.shortcuts import render

# Create your views here.

def home(request):
    x = 1500
    y = 1500
    result = (x >= y)
    return render(request, 'home.html', {'result':result})

We define two integers, x & y, and then use the greater than or equal to an operator to compare them. We render the result on the HTML page.

The home.html file:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>PythonGuides</title>
</head>
<body>
    <p>
        <b> X is greater than or equal to Y: </b>{{result}}
    </p>
</body
</html>

In the home.html file, we are just using the result variable to get the output. In the end, we will get the following output.

Compare two integer in template

In this section, we’ll learn how to use Django’s template tag to compare two integers. Let’s, clarify our concepts by using various examples.

Syntax:

{% if variable boolean_operator value %}

        Statement To Print

{% endif %}

I’ll show you the project’s urls.py and app’s urls.py file before I start the demonstration. As it remains the same in all of the examples.

The Project’s urls.py file:

Here our project name is PythonGuides.

from django.contrib import admin
from django.urls import path, include

urlpatterns = [
    path('admin/', admin.site.urls),
    path('', include('home.urls'))
]

This means that when you open your project in the browser, it will take you to your home.urls.

Now, see the home urls.py file:

from django.urls import path, include
from home import views

urlpatterns = [
    path('', views.home, name='home')
]

It moves to the views.py file of the home app.

Example #1

In this example, we are using the equality template tag to compare two integers.

The views.py file:

from django.shortcuts import render

# Create your views here.

def home(request):
    x = 100
    y = 150
    return render(request, 'home.html', {'x':x, 'y':y})

Firstly, we will create a view that will redirect to an HTML page. In the views.py file, we define the numbers and redirect the numbers to the home.html page.

The home.html file:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>PythonGuides</title>
</head>
<body>
    <p>
        {% if x == y %}
        {{ x }} is equal to {{ y }}
        {% else %}
        {{ x }} is not equal to {{ y }}
        {% endif%}
    </p>
</body
</html>

Here, we add an equality boolean operator in the template using {%if%} tag. It tag evaluates the variables, if the condition is “true” the contents of the block are output.

The output is as follow:

compare two integer in template
Equality Template Tag

Example #2

In this example, we are using the less than template tag to compare two integers.

The views.py file:

from django.shortcuts import render

# Create your views here.

def home(request):
    x = -10
    y =  10
    return render(request, 'home.html', {'x':x, 'y':y})

To begin, we’ll make a view that redirects to an HTML page. We declare the numbers in the views.py file and redirect them to the home.html page.

The home.html file:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>PythonGuides</title>
</head>
<body>
    <p>
        {% if x < y %}
        {{ x }} is less than {{ y }}
        {% else %}
        {{ x }} is greater than {{ y }}
        {% endif%}
    </p>
</body
</html>

Here, we add less than the boolean operator in the template using {%if%} and {%else%} tag. If the tag evaluates the variables, If the condition is “true” the contents of the block are output, otherwise, else tag contents block is output.

compare two integer in template tag
Less Than Template Tag

Example #3

In this example, we are using the less than or equal template tag to compare two integers.

The views.py file:

from django.shortcuts import render

# Create your views here.

def home(request):
    x = 150
    y = 150
    return render(request, 'home.html', {'x':x, 'y':y})

To begin, we’ll make a view that redirects to an HTML page. We declare the numbers in the views.py file and redirect them to the home.html page.

The home.html file:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>PythonGuides</title>
</head>
<body>
    <p>
        {% if x <= y %}
        {{ x }} is less than or equal to{{ y }}
        {% else %}
        {{ x }} is greater than or equal to {{ y }}
        {% endif%}
    </p>
</body
</html>

Here is the output:
