Let's do a step wise solution of your question:-

<blockquote>
 Always be running in the background on boot.
</blockquote>

<ul>
<li>For that you have to save your code as a .<code>pyw</code> file (notice the <code>w</code>
in the end). The difference between a regular <code>.py</code> an a <code>.pyw</code> file
is that, <code>.py</code> invokes console (~commandline) equivalent tool for
execution and executes in foreground, on the other hand a <code>.pyw</code> file
runs in the background at all times (i.e the console won't show up).
So it won't require you to manually open the console at all times for
executing the script as the script will be running in the background
at all time.</li>
<li>Copy this python file in the startup folder of your OS (any file in
this folder will automatically execute once the operating system has
booted). What this will do is when OS will boot, your python file
will automatically start executing in the background, so you won't
have to manually launch it at every system startup. And since it is
in the background it won't interfere with your work. (if you're on
windows OS, you can access your startup folder by typing
<code>shell:common startup</code> on your run and pressing enter) (adding files
to this folder requires root privileges. If you are unable to get to the folder, then <code>C:\ProgramData\Microsoft\Windows\Start Menu\Programs\StartUp</code> is its default path on windows 10.</li>
</ul>

<blockquote>
 To check whether the desired program is opened or not?
</blockquote>

For that use this code:-

<pre><code>import win32com.client
import os

# This infinite loop ensures that the program run's at all times 
while 1:

 # Halting the execution of the program for 5 seconds
 # This will act as a bottleneck to reduce resource usage of this program
 os.sleep(5)

 wmi=win32com.client.GetObject('winmgmts:')

 # change the value of this variable with your application name
 program_name = "chrome.exe"

 for p in wmi.InstancesOf('win32_process'): 
 if p.Name == program_name:
 # Add code for launching your desired application from here 
</code></pre>

The above code will check all the current running processes, and try matching their names with program_name variable. Change the value of variable program_name with the name of the program that you want to check, is running or not. (This process will happen once in every five seconds)

NOTES:-

<ol>
<li>If several instances of the you program are running, (ex. <code>chrome.exe</code>
alone runs as several processes), then <code>p.Name == program_name</code> will be
true several times for a given name. </li>
<li>Program name is cases sensitive. i.e chrome.exe and Chrome.exe are
treated differently, so mind the case while providing value to the
<code>program_name</code> variable.</li>
</ol>

<blockquote>
 Launch the associated application
</blockquote>

There are a dozen ways in which you can open a application of your choice in your OS. The choice depends on what you are willing to do with your program, after its execution.

I would recommend <code>Popen</code> of library <code>subprocess</code> for your use case, as you want to provide different inputs to the application after you had opened it up.

<blockquote>
 Perform any actions in the applications I.e. create new project for me.
</blockquote>

<a href="https://stackoverflow.com/questions/247724/how-can-i-launch-an-instance-of-an-application-using-python">This</a> question definitely is what you looking for. There are different ways to accomplishing this too, where the choice/path depends on use case (like the previous one).

To automate the process of opening up a group of related applications, the Python script would need to 
1) always be running in the background on boot. 
2) check every few seconds if the trigger software has been opened.
3) launch the associated applications.
4) perform any actions in the applications I.e. create new project for me.

I have no prior experience with this but this is relevant to optimizing a few things on my Windows pc. 

Anyone with the knowledge and courtesy to help, and the time, please do so.
Thanks.

How to make a backgrond script that opens programs if another program is opened?

要自动化打开一组相关应用程序的过程，Python脚本需要1)始终在引导时在后台运行。2)每隔几秒检查一次触发器软件是否已打开。3)启动关联的应用程序。4)在应用程序中执行任何操作，例如为我创建新项目。我以前没有这方面的经验，但这与在我的Windows pc上优化一些东西有关。任何有知识和礼貌的人都可以帮助，而且有时间，...
