I want to run multiple programs in parallel in Spyder. How do I do it? I tried deactivating Use a single instance under Preferences---Applications but this didn't help.

I have two Python concurrent-related questions that want someone's clarification.
Task Description:
Let us say I set up two py scripts. Each script is running two IO-bound tasks (API Calls) with multithreading (max workers as 2).
Questions:
If I don't use a virtual environment, and run both scripts through the global Python interpreter (the one in system-wide Python installation). Does this make the task I described the single process and multithreaded? Since we are using one interpreter (single process) and have two scripts running a total of 4 threads?
If I use the Pycharm to create two separate projects where each project has its own Python interpreter. Does such a setting turn the task into multiprocessing and multithreaded? Since we have two Python interpreters running and each running two threads?
Each running interpreter process has its own GIL that's separate from any other GILs in other interpreters that happen to be running. The project and virtual environment associated with the script being run are irrelevant. Virtual environments are to isolate different versions of Python and libraries so libraries from one project don't interfere with libraries in another.
If you run two scripts separately like python script.py, this will start two independent interpreters that will be unaffected by the other.
Does such a setting turn the task into multiprocessing and multithreaded?
I don't think it's really meaningful to call it a "multiprocess task" if the two processes are completely independent of each other and never talk. You have multiple processes running, but "multiprocessing" within the context of a Python program typically means one coherant program that makes use of multiple processes for a common task.
I have scheduled a python web-scraper to run everyday at specified time. This puts load on spyder memory after a while results in system crash. Is there a way to solve this issue?
I had the same problem with using Spyder IDE for a process that I was running.
Things like deleting variables and using gc.collect() didn't work to free memory within a loop for my script on Ubuntu 20.04.
The way I got around having memory crash problems in long loops inside of Spyder was to run the script in terminal instead of Spyder using python my_script.py. This worked for me and my loops or long processes aren't crashing my memory anymore! Goodluck!
How can I execute three or more Python scripts in parallel?
Currently I am executing three Python scripts in three different consoles of Spyder.
One solution could be to import all the scripts and then simultaneously execute them in a function.
I am trying to create a file sharing program using Python and to do that I am using a server. In order to test the program I need to use a different Python IDE to run the server and then use Sublime Text 3 to run the client. If possible, I would like to know if and how I can run both programs simultaneously in Sublime Text 3.
I feel it may just be best to run the python files via the terminal or command prompt. This would also in general be a better practice to run your programs. To run them, you would just need to type in... "python path/to/your/python/file"
Each window gets its own build process. You can open both files in separate windows, run the build on the server, then run the build on client and they will both run simultaneously.
I'm using Enthought Canopy to run my python code. On one computer I want to run 3 different python codes, all completely independently (for 3 different instruments), simultaneously. I seem to only be able to run one code at a time in Canopy with one kernel. How do I run more at the same time?
I have read in a thread about using ipython qtconsole, but I don't know what this is. I can't even find this file on my pc. Can anyone step me through the process of how to get these codes all running on multiple kernels?
