After building a flutter web app with
flutter build web
I want to deploy this with dango server, what should i do?
I'm assuming that your backend is an API Rest and does not render the HTML.
The "right" way will be to have a service for the SPA, and another for the API. For example, with docker, droplets, kubernetes, DO and Heroku.
Another way that I'm thinking is... you specified a route (like example.com/) to serve the flutter web project (I mean the HTML), and the other routes can be the endpoints.

On my website, I have an upload directory, with an upload.html page. I want to be able to send the upload to an external CDN, which is an AWS bucket. According to this post, it can't be done using PHP, however I was wondering if I could do this using Python. I don't have any code, because I have no idea where to start. Maybe I can interact with the AWS CLI using Python?
Thanks for any help.
You can do it with AWS PHP SDK as well you just sync the uploaded files to S3 Bucket
$client = S3Client:::factory(array(
'key' => 'your-aws-access-key-id',
'secret' => 'your-aws-secret-access-key'
));
$client->uploadDirectory('/local/directory', 'my_bucket');

Say you write a python application that interacts with a webserver. The application secures your traffic with public-private key encryption (e.g. RSA). How can you prevent someone to read the program in a normal text editor and extract your private key?
Usually user applications that interact with a webserver have 2 methods for authentication.
1-Session authentication: you need to login to the webserver for the server to give you access to the pages or information you need.
2-Token authentication: The server can generate a token that the user can send with the requests.
On the other hand if its an application that only you are going to use you can set the private keys in the environment variables of your operating system and then fetch them using python.
API_SECRET = os.environ.get("SECRET_KEY")

I am new to Google App Engine. I am building a web app using python and django rest api framework. I am using cloud bigtable, cloud sql and cloud storage for my databases and storage. I wanted to know if I have to use Google App Engine Apis or can I build my own in django to read and write data to the databases and get files from cloud storage? I want to try to keep costs low and not lock in to Google App Engine.
You can use vanilla DjangGAE to do everything you'd mentioned. A good starting point
It's worth mentioning that there are a few notable limitations. Those are also listed in the site I'd linked to.

I am learning Flask and I want to practice by making simple web app.
I want to make a chat web app that allows sending messages between two or more web browsers in Flask but I am not sure where to start or go about building this application. This question is pretty broad but what I want to know is how to structure this application. What are the pieces I need to build this application.
very broad question, but I'd recommend starting here with web sockets http://blog.miguelgrinberg.com/post/easy-websockets-with-flask-and-gevent . Then you can have two member subscribe to a channel and make messages to each other.

How can I create a client side database to store information of users on client side. Does anybody know of any tutorials or pointers? Which is the recommended database to use? My client is in .js and uses Django framework.
What you are asking for is called Web Storage and is part of HTML5.
http://diveintohtml5.info/storage.html
http://www.gwtproject.org/doc/latest/DevGuideHtml5Storage.html
However, many times when people SAY they need a client-side database, I ask them the details and it turns out that they don't really need client side storage at all, so proceed with caution.
