Django is a high-level Python-based free and open-source web framework, which follows the model-view-template (MVT) architectural pattern.
It is maintained by the Django Software Foundation (DSF).
Django's primary goal is to ease the creation of complex, database-driven websites.
Some well-known sites that use Django include the Public Broadcasting Service, Instagram, Mozilla, The Washington Times, Disqus, Bitbucket, and Nextdoor.

ur energy while explaining anything : always super energy

[vinayak]

This one is a very important video. many of other tutorials in youtube did not give this kind of actual operation. By seeing this, I could do what i want to do in my code. Thank you very much

[ihcc]

You made it super simple. I have spent hours watching countless tutorial but couldn't get it. Great Job Telusko

Flow explained above SIMPLIFIED:
Here we need to enter 2 numbers, add them & print result in new page.
1. In the home.html create a form to add 2 numbers home page.
a. Need 2 text fields to get values & button to submit it.
2. Need a page to display the results (result.html) - create it.
3. Created a new page, need to register in "urls.py".
4. Now, page is created & registered in URL's => now we need logic for it.
a. Create a function to add in "views.py" which gets the response from "home.html
b. And return to "result.html
5. Finally, in "result.html" receive response in a variable.
6. DONE.
Create a page -> register it in urls -> write logic in views -> receive in results.

To convert the inputs to integer, the int() function works good, even with double quotes. Perhaps in this video, the refresh didn't work correctly.

Great explanation sir. I really like your tutorials.

When you add 5 plus 6 you get 56... this one was awesome Sir!!! Love your lectures....

1:00 form
5:00 As a client, When you send a request to this server, you basically sending an object and that object will have some values (num1, num2)
When server send you value back, it will be in a format of response
7:40 <form action="add"> add 빼먹지 말자.
Thank you

Anna, super anna! Chala baavunnai tutorials. Nee teaching, energy kuda adirindhi.

[christcentric]

For those who are not getting the result page when clicked on submit please note that <form action ="add"> in this code it should be <form... Dont give any spaces after <... Hope this helps

[hasibjoy]

When 1st you didn't called for int of num1 a d num2 I just thought 'How a champ like you can miss it.' Letter I got this the way of your teaching. nice way

[olkhovskyrus]

Another solution to add numbers but not strings is to wrap variables in int() as we sum them.
In my case it was
c = int(a) + int(b)

I am watching all videos of Python, but when result comes 56 it's make laugh for me. It's commonly happen with developers. I have also faced this type of incident, before 4 year ago when I am coding with PHP. But your tutorial is awesome. I have learned lot's of concept of Python. Thanks to making this tutorials.

[siddiqzaryab]

Hey, Navin! Is it absolutely necessary to have knowledge of HTML/CSS and JavaScript before starting Django or Can we learn it as we work on Django along the way? Your tutorials are awesome by the way. :)

[varunkrishnaKyathanpally]

Awesome tutorial. I understood that once we practice Django more, we can play with it.

[manpreetkaur]

Excellent stuff... I always watch your tutorials whenever get stuck...

[sauravrai]

Great explanation and love the energy and passion which you teach :)

[abdelolayyan]

Thanks pro Excellent tutorial; I would rather name it {'resultVar':res} to be clear for the student and not confused . Thanks

[sayantanmitra]

Sir i did exact same things but still when I runserver i get 2:53 this exact issue plz help have almost spent an hour searching for the sol.

[nrknithin]

Video was super informative, but i dont think the second time u got 35 when adding 3 & 5 was because u needed to pass single quotes, I think it was just same cached pages
