I had a requirement of migrating twisted to FastApi.
The old code was completely written in Python 2.7 and used JsonPrc along with twisted client.
Like - [https://stackoverflow.com/a/4738563][1]
Even the static content like html,css,js files used jsonprc to access the API calls. Like there is a complete index.html file which has dependency on html,css, js with jsonprc calls.
I have gone through some documents but couldn't come to conclusion.
Below were few links-
https://github.com/smagafurov/fastapi-jsonrpc
https://github.com/authorizon/fastapi_websocket_rpc
In these I cant see how to integrate html,css,js with jsonrpc. for eg., index.html
So I just want to know the approach to achieve my requirement.
Like websocket, jsonrpc or jinja Template ? Thanks
Is your main issue to serve static files? FastApi has an easy dedicated solution for that: https://fastapi.tiangolo.com/tutorial/static-files/

I am proficient in Bash and a beginner in Python (I have some experience with Flask and Requests).
I wrote a Bash script which asks for some input (four strings) and creates a configuration file based on that input. That's good for me, but I would like to convert it to a (no frills) web interface. I know how to configure Apache, if necessary.
I know there are zillions of ways to do that. I'd like some hints on how to tackle my problem, ideally using Bash or Python. By the way, I've used Octave on CGI for some of this in the past, and I think it's excellent for math purposes, but I'd like to get ideas about some simpler, more generic avenues.
I would create a Django site for this. It can be setup really quickly. I would recommend you host it on PythonAnywhere. They have a free tier, and works really well. Django is similar to Flask, but I personally like Django. If you could be more specific on what your App needs to do, some sample code could be provided.
You probably just need the right keywords to go the right direction. From a high level all you need to to is two steps:
Create a static html web page that contains a form. This form contains at least one input field and a submit button. The URL it accesses needs to be understood by your webserver to invoke your script via the common gateway interface (CGI).
write a python or bash script that Apache can invoke via CGI that receives the value and does something about it. The stdout of this script will be returned back to the browser, so it better be HTML again.
For details check out http://httpd.apache.org/docs/2.4/howto/cgi.html

so my python application opens a link that would be found in my config file. I would like to make it so it would like to allow it to go to the website without doubling the %. Heres what I would want config.get('CONFIG', 'Website') the web address has a bunch of %'s in the link but when I run it, the process ends
I'm assuming you are using the configparser module?
If so, you can use ConfigParser(interpolation=None) to disable string interpolation (which controls the behavior of % characters in the config file).
(Or on older versions of Python, you may need to use RawConfigParser instead.)

Basically I want to create a sexy GUI using HTML5 then call code that I wrote in python. I have just discovered some tutorials about web2py, however I am getting the videos now from youtube so I can only watch when I get home. (Life of a student with no internet at home).
So basically I have written a python script, now I want to use a webpage to interact with that script instead of terminal as I have been doing. So I have a webpage provide me the GUI to my python app.
Hope this makes more sense.
Any help and direction will be greatly appreciated.
Thanks in advance
You need to flip that around, you want to run server-side python code that renders your sexy HTML5 GUI. There are many Python frameworks that are suitable to this, including web2py, django, and my personal favorite flask.
Any of these frameworks will let your python code run, then render the HTML with python variables/functions available by using a templating engine (for example Flask uses Jinja template). Tutorials are readily available for all of these python libraries, but if you want to take a look at Flask, I can recommend Miguel Grinberg's excellent tutorial series.

I'm new to web development and going to make a website which responses with data received from request to web-service(facebook for e.g.) and how to choose what is more useful here:
nodejs has an callback model which allows not to wait while gathering data for user from other services (but i've broken my fingers and my brain after trying to make a kind of class in javascript with inheritance and the whole server drops after unhandled error in script)
python is very convinient in working with diff. kinds of data, it's more convinient for me, former C++ developer
yesterday i've read about twisted python that also uses callbacks
Help me please to choose what to use, better - performance, simple code
The callback model might make your code more verbose but WAIT! there is a solution! Check out
waitfor.
Anyway, if it's a personal project then no one is forcing you to use node.js for webapp development.You should go with what makes you more comfortable. If you like developing in python then go for it! :)
why don't you try django; it uses python (which you said is more convenient) and is also very commonly used for web development.

There is a lot going on in web frameworks - they can take an age to learn.
So, what is it I am missing when I say that WSGI defines pretty much all we need to respond to a request. If I overload the environ dict I can store almost all I need, so what am I gaining from a framework?
You can certainly write a web application using only WSGI, but at some point you're going to have to solve the following problems:
How do I handle different url requests?
How do I parse form data?
How do I render a response?
How do I support sessions?
How do I persist data?
etc, etc, etc...
Each web framework solves some (or all) of these problems. Yes, you could design and implement solutions yourself, but web frameworks contain solutions that other people have found work very well for them. So that's what you get from a framework: a bunch of suggestions for how to solve common problems when writing web apps.
Finally, it's easy to be overwhelmed by the number of choices for web frameworks, but if you just learn one, others will be much easier to understand. I would recommend learning either django or a more minimalist framework like flask. Other frameworks are pretty similar to these two, and you'll be able to pick them up easily.
