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>
