In this tutorial I will show you how to add two numbers in django framework python program.
urls.py:
Defame the URL pattern to map the view.
from django.urls import path
from . import views
urlpatterns = [
path('addition/', views.addition, name='addition'), ]
views.py:
In django view render the template and handle the form submission.
def addition(request):
if request.method == 'POST':
try:
num1 = request.POST.get('num1')
num2 = request.POST.get('num2')
result = eval(num1) + eval(num2)
context ={'result' : result}
return render(request,"app/addition.html", context)
except Exception as e:
print(f"Error: {e}")
return render(request,"app/addition.html")
addition.html:
Create a simple HTML form with two input text boxes and submit button field. On form submission you can handle the addition operation and return the result.
<div class="container" style="margin-top:100px;">
<div class="row">
<div class="col-12">
<h2> Addition </h2>
<form action="{% url 'addition' %}" method="post">
{% csrf_token %}
<label for="num1">Number 1: </label>
<input type="text" name="num1" class="form-control">
<label for="num2">Number 2: </label>
<input type="text" name="num2" class="form-control"> <br>
<button type="submit"> Add </button> <br>
<p> The result is : {{ result }} </p>
</form>
</div>
</div>
</div>
