I'm trying to write a karaoke program in python. Every karaoke software has basic functionality like seeking in the video as well as modulating the pitch of music by half steps. What are some modules that I can use to permit this functionality?
I'm going to use wxPython to write the gui portion if that makes a difference!
Honestly you might want to take a look at PyGame - it has fairly robust libraries for handling stuff like music and movies: http://www.pygame.org/docs/
wxPython has a built in media controller, wx.MediaCtrl, which can play both audio and video. It has most of the basic functionality built in, like seek, pause, etc. I've found it very easy and reliable.

I started working on some beginner projects and games to test my abilities.
I found that all I was doing is simply writing a code and seeing the ugly output next to it (in the interactive window). The code works, but that's not how I want a normal user to interfere with it.
I'm looking for a way to display my python program properly to a user. Is there some sort of interface manipulating that I should learn in order to accomplish that? thanks.
It sounds like you're seeking to build a GUI for your programs.
In several of my early projects, I used the built-in Tkinter module to accomplish what you're suggesting. It may not give you the most modern-looking GUI, but it's nice to use due to it being included with Python by default and the abundance of documentation and tutorials.
There are tons of great videos on YT that walk you through step-by-step on everything from pop-up, dialog-box messages, to full on user-input, menu-laden GUIs. Just search "tkinter tutorials".

I want to develop a script in python that can be used to identify a video clips contained in a video stream.
Could you please suggest me some python libraries or any example scripts to start compare to video files
Thanks
This may be of use - it is image rather than video but the same principles will apply:
https://realpython.com/blog/python/fingerprinting-images-for-near-duplicate-detection/
More generally, the technology you are most likely interested in is usually referred to as video fingerprinting. This is a fairly dynamic domain so its worth doing some googling to get a feel for the latest state of the art.

I am quite fluent in Python, but have only really used it for data analysis.
I would like to learn how I can interact with webpages. For instance, I want to start by writing a code that will press a button on a webpage for me.
I just don't know where to start or what to google to find resources about this.
Could anyone point me out in the right directions, or suggest some key words that I could search for?
Thanks.
Have you tried to use the pyautogui module, which allows you to programmatically control the mouse and the keyboard?
An example of an automatic form filler on a webpage is available in chapter 18 of the Automate the Boring Stuff with Python book.

I am teaching art students the basics of Python and it would be very convenient to add some graphics (drawings, pictures, etc.) in the comments within the code instead of "just" code and text comments.
I have seen some friends using Mathematica and exchanging beautiful files that include graphics, comments, pictures, etc.
Does such a thing exists for Python?
Have you looked at the iPython-Notebook? It allows you to write/run code and use html for notes. If you know html it will be easy to add graphics in too. Not sure if that exactly answers your problem, but it is definitely a nice tool

I've taken to creative coding on my iPad and iPhone using Codea, Procoding, and Pythonista. I really love the paper.js Javascript library, and I'm wondering how I might have the functionality that I find in paper.js when writing in Python.
Specifically, I'd love to have the vector math and path manipulation that paper.js affords. Things like finding the intersection of two paths or binding events to paths (on click, mouse move, etc).
There's an ImagePath module provided by Pythonista that does some path stuff but it's not as robust as paper.js (it seems).
Any ideas?
The ui module actually includes a lot of vector drawing functions, inside a ui.ImageContext. ui.ImageContext is a thin wrapper around part of one of the Objective-C APIs (maybe CALayer?) The drawing methods are designed to operate inside the draw method of a custom view class, but you can present these things in other contexts using a UIImageContext, from which you can get a static image.
