Remap alt+tab hotkey for a certain app Python

I am trying to create a python programm where it will check if the app i want is open(e.g. Minecraft) and if it is, when the app is in the foreground i want to remap Alt+Tab to press F11 and then minimize the window as like pressing the minimize button of the window. For minimizing i don't want to use the hotkey WindowsKey+M. If there is another way i can achieve that, it's ok with me and i would like to test it, but i would prefer if you could help me with creating the programm. That's the gist of it, if you need a better explanation or anything else i'll try to help you any way i can. Thanks in advance! Also i am using Python 3.7.
EDIT:
I used AutoHotKey in order to achieve the remaping but then alt+tab loses it's original functionality. I would like to prevent that. Here is the script i created:
!Tab::
if WinActive("ahk_class Minecraft")
{
Send, {F11}
WinMinimize
Return
}

Adding ~ as prefix will preserve the hotkey's original functionality.
In the documentation (Hotkeys | ~):
When the hotkey fires, its key's native function will not be blocked
(hidden from the system)
Change your code to ~!Tab::

How do I send key presses and mouse movements to an application running in the background? (In Python)

Ok, so what I want to do is allow my program to send mouse movements and keypresses (both mouse and keyboard) to a particular task without having to be tabbed into the task so I can do other things on my computer with the mouse and keyboard while the task runs. Is it possible to do this relatively simply with existing python modules?
example of what I want to do:
task='application name'
task.leftclick
task.moveX(int)
task.moveY(int)
task.keypress(r)
All while being able to use my mouse and keyboard normally on a different application.
Thanks for the help in advance!
(Python3.6)

For anyone who happens upon this post, I found https://pypi.org/project/ahk/ I haven't looked into it fully but either you can use this or create an auto hotkey script and just call that with you python code to achieve what I wanted to do in the question.

interacting with a user created gui dynamically using python

There is a user created GUI which is an .exe that loads a DLL. This GUI has a bunch of sliders, check boxes etc. I would like to move two sliders at the same time using python automatically without me using my mouse to move the sliders. I would like to know the python modules that an be used to achieve this purpose.

You can try using SikuliX.
It can be used to automate mouse or keyboard actions based on pattern matching. It is originally developed for Java I think, but it can be used with Python.
Basically, anything you can do yourself manually can be done with it.
The developer seems to be pretty active, so you can easily seek help from him if you have issues.

Background python program inspect GUI events

I am thinking of writing a python program that runs in the background and can inspect user's GUI events.
My requirements is very simple:
1) When user right click the mouse, it can show an option; and when this option is chosen, my program should know this event.
2) When user select a file and click some predefined key combination, my program should know this event.
What should I do? Is this a GUI program? I am also thinking that, this program maybe a daemon on the machine and can inspect the user's GUI event, but I am not sure how can I do this.
Thanks.

If you're talking about doing this stuff inside of a wxPython program, then it's all pretty simple. There's a PopupMenu widget for the first one and an AcceratorTable for the second one. If you're wanting to catch mouse and keyboard events outside of a wxPython program, then you have to go very low-level and hook into the OS itself, which means that there really isn't any good way to do it cross-platform. You'll probably want to look at ctypes and similar libraries for that sort of thing.

I've been researching this problem a bit and while I don't have a definite answer, I thought it would be good to share what I found.
First, according to the answers for this question, wxPython cannot track nor control the mouse position outside of the area controlled by the wxPython app. However, as we can see in the answers to this question, under certain circumstances it may be possible to create system-wide hot keys that wxPython can see (although we can also see that this is probably not the optimal solution).
So what will work for the OP? Well, build a cross platform application that does what the OP wants seems almost impossible so I will assume the OP is developing for MS Windows. Following the suggestions in those previous two questions, I looked into the PyWin32 API. It's a little hard to find documentation for it but this question offers some helpful links. A little more digging and I found this tutorial for system-wide hotkeys as well as the win32event.WaitForMultipleObjects and win32event.WaitForSingleObject methods which, if the OP can figure out the proper event, may be what the OP needs to catch menu clicks.
I know it's far from a complete answer but hopefully this can serve as a good jumping-off point for further research.

Waiting for a program to finish its task

I'd like to know how to have a program wait for another program to finish a task. I'm not sure what I'd look for for that...
Also, I'm using a mac.
I'd like to use Python or perhaps even applescript (I could just osascript python if the solution if for applescript anyway)
Basically this program "MPEGstreamclip" converts videos, and it opens what appears to be 2 new windows while it's converting. One window is a conversion progress bar, and the other window is a preview of the conversion. (Not sure if these actually count as windows)
(Also, MPEGstreamclip does not have an applescript dictionary, so as far as I know, it can't listen for certain window names existence)
But basically I want my program to listen for when MPEGstreamclip is done, and then run its tasks.
If it helps, when the conversion is done, the mpegstreamclip icon in the dock bounces once. I'm not sure what that means but I'd think you could use that to trigger something couldn't you?
Thanks!

I realized GUI applescript was the answer in this scenario. With it I could tell the PROCESS to get every window, and that worked. However, I'm leaving this up because I'd like to know other ways. I'm sure this GUI workaround won't work for everything.

If the MPEGstreamclip actually ends when it is done, you could wrap the whole thing up in a python script using various techniques already discussed in another post. Just be sure to wait for the external process to end before continuing with your other steps.
