I have PyCharm, Visual Studio Code and Jupyter Lab installed on my PC, and the PC has Python 3.11 installed?
Would someone please educate me on this topic?
If I want run 3 Python programs simultaneously (each program uses its own IDE). Would each IDE run faster if each IDE has its own Python program? Right now all IDEs are using the same Python 3.11 and things are working fine. Just for my own knowledge, I am just curious of this topic. Thank you in advance for educating me!
You have to discriminate the two following concepts: program and process.
Program
A program is a list of instructions. It's generally written on a file.
It can be a binary text but also an ASCII text.
A program does nothing. It is basically a static text.
Process
A process is the execution of a program by your operating system.
A process has a dedicated memory and execution time. Its role is to "play" your code, instruction by instruction.
In your example, python.exe is a program.
When you execute it, your operating system will create a dedicated process.
So, when you run several IDEs, you simply run several process of your same program.
Thus, there is absolutely no loss in terms of performance.

I recently started using Python. I realized that even the simplest program starts a Python process that never ends and causes my computer to overheat if I don't manually kill that process.
I've even seen multiple Python processes running at the same time after running a few easy Python programs (Hello, World!) in a row.
I updated to the latest Python version (Python 3.9.3), installed all the Certificates, and tested a few different programs to see if it happens every time—it does. I am using VSC as the IDE but the same situation happens even if I use IDLE.
My questions are: Is this an interpreter issue or a Mac issue? Can it be fixed?
Thank you very much.
Firstly, I have very limited experience with programming. So please bear with me.
I am using a custom software, called deformcyto, made for my lab which can only be started via anaconda prompt. I need to call the same program multiple times but with different inputs. Can I write a python script which would keep calling the program with new arguments?
Thanks for any pointers!
You can try something like this, if your program is an executable.
os.system(r"C:\youdir\..\yourprogram.exe")
You can also write a bash script or a powershell script and start the program multiple times with different arguments.
I've created a simple script that executes a "moving mouse and keyboard" sequence. Although currently to get this to work I use a Shell (Idle) to run and that is to slow with boot up time and such.
Is there a way to have this python file on desktop och with a hotkey swiftly run the code? I tried doing it through terminal but it doesn't like my module.
Some info:
This is for both mac and windows.
The module I imported is pyautogui from PyPi and it works in the shell.
Thank you in advance!
Some things to consider when trying to setup a hotkey to successfully execute any kind of command:
Each Operating System has its own ways to setup hotkeys and sometimes this may differ between distributions as well as between desktop managers.
Many of the relevant how-to-descriptions are easily found via regular search machines as Google.
If you would in fact like your script to set-up its own hotkeys you would have to re-write it in such a manner that it can detect the current operating system/distribution/desktop manager by itself and execute the commands relevant to that particular set-up.
Am doing my project in raspberry pi. I have written programs in python and also in node.js . I want to run these programs depending upon some conditions. And all these things should be done just by clicking in a single executable file. Can anyone help me out citing how it can be done? Can Shell Scripting satisfy my need?
If you can determine that some conditions from shell script, then shell scripting can satisfy your need. That depends on what will be the condition.
As an alternative solution you can write another short program in node.js or python that will do the job.
I'm new to Python programming.
My question is where to write python programs in linux--
in terminal or
any writing pad like gedit etc
Should we write one program again and again for running or we should call the program and run it.
After you install Python (it's installed by default on most Linux-es), you have two options:
Terminal. Just type python <ENTER> and you will be taken to the Python interpreter interactive prompt. For anything but the most basic stuff, however, you may want to intall IPython - an alternative interactive prompt that's much better than the default one.
In a file. Save your code into a .py file and run it with python myfile.py
But first and foremost, start by learning Python - the official tutorial is a great place to start. Among other useful information, its chapter 2 discusses how to use the Python interpreter for beginners.
Stackoverflow also has a lot of great resources for learning Python. This question, for example, and many others.
If you are learning, or you are evaluating expressions, you could run Python in terminal, or use IDLE.
But if you are writing large chunks of code, then you should consider using an IDE.
You could either use Geany, or use Eclipse with PyDev. I prefer Eclipse myself.
For running, you can run it using the command python program.py, or just add the line
#!/bin/python
to the beginning of your program, grant it execution permission using chmod, and run it with ./program.py command.
