I want to create a new cytoscape app for analysing protein interaction but I don't know if I can use python or just java.
Great question. This is within scope of this forum.
The answer is "it depends". Cytoscape apps themselves must be Java (or something that runs in JVM, though there's only documentation support for Java and the forums will give best advice for Java).
However, the Cytoscape Cyberinfrastructure (CI) allows Python-based services (e.g., the Diffusion service) called by Cytoscape apps (e.g., the Diffusion app). The service must be deployed somewhere on the web (e.g., in a Kubernetes cluster).
If you'd like help with that route, you'll find enthusiastic support ... please e-mail the cytoscape-app-dev at googlegroups.com forum directly.

For a college course, I have to produce a coding project over the course of 1 year. My current idea is a neural network that detects an image, processes what that image is, then reads it aloud in 2 different languages. My idea is to make this a website or a mobile app, and to use Python. Is this too ambitious? Or not ambitious enough? Or should I look at something completely different?
There are many approaches for your project. I‘ve listed some of them here.
For your website/app itself:
Either use a Python Library like Flask, Django or web for the backend part.
Even though plain HTML/CSS/JS would be enough for your frontend part of the project, you might use jQuery for simplifying the upload process of an image.
Image Classification:
To classify an image, you can either use a library like Tensorflow or PyTorch or just use an API like imagga (saving you a lot of work).
Now, turning the result to speech can be made possible by using Google‘s Text-To-Speech library „gtts“.
I hope I could help you,
wish you luck for the project 👍!

I don't get the benefits of using TA-Lib abstract ¿is it speed? ¿less processing? I went through the documentation, examples, and code examples, but can't get it. ¿can anyone explain it?
EDIT: This question is not opinion-based, as you can see in the answer, it's about performance of the function API vs abstract API of ta-lib
This API allows you to list all TA functions implemented in DLL (because python's ta-lib module is just a wrapper around compiled C library) and call them by indicator name (a string), instead of hardcoding switch with 200+ cases and rebuilding your app every time TA-lib adds new indicator. It also allows you to get info about data that indicator requires which may be used to adjust UI for end user asking him to enter the required data. So this API is designed not for a python data scientists who play with single TA indicator, but for desktop and web programmers writing GUI applications or web services addressed to wide audience. There is no any performance benefits.

I have a working R script. Can this be wrapped in a Python code so it can be deployed as an API ?
As mentioned in an earlier post, things that are not easy in R can be relatively simple in other languages. Another example would be connecting to Amazon Web Services. In relation to s3, although there are a number of existing packages, many of them seem to be deprecated, premature or platform-dependent. (I consider the cloudyr project looks promising though.)
If there isn’t a comprehensive R-way of doing something yet, it may be necessary to create it from scratch. Actually there are some options to do so by using AWS Command Line Interface, AWS REST API or wrapping functionality of another language.

I'm a learning Python/Django programmer and want to try to create an easy web-messenger. Is it real to write web-messenger for django? And does any modules for that exist or any open-source protocols support python?
Or you can install xmpp server (like eJabberd) and write a server side interface over it. It will be easier, faster and optimal solution.
Gmail and Facebook both uses xmpp protocol. People using your application will also be able to send chat request to their friends in gmail.
You wont even have to write a website interface, there are javascript library (like Converse.js) available which you can directly plug into your website and you will be good to go.
Not sure what you mean by 'web-messenger'. Do you mean a chat system? Django have plenty of chat apps that you can integrate into your projects.

Web2py looks like a very nice Python framework but I am wondering if it is suitable to use for a large public web site. What sorts of issues might I run into? I'm not worried about technical scalability so much as UI/UX limitations, ability to connect other components, etc.
web2py is a very capable web server application framework. UI/UX (User interface / Experience) limitations does not arises usually from a server framework.
There are quite a number of free application that demonstrates it's capabilities:
http://www.web2py.com/appliances
If you want to compare it with other server frameworks, there are quite a few documents out there that you can read on.
Django, Turbo Gears, Web2Py, which is better for what?
The following discussion should add to information here
Anyone out there using web2py?
You have to be more specific to make a judgement or evaluate a server framework than what you have mentioned.
[Edit: based on comments]
While the examples in the link provided by mdipierro may not inspire confidence with regard to desired UI/UX solutions. It would be premature to consider that because of web2py or any other server framework. It might point to the fact that all these are implemented by a resource constrained team.
You might take a look at this list of sites powered by web2py.
