I want to paste my code from my text editor into the IDLE window, but when I do the program won't run. Is there a way to run my program without copying and pasting into the IDLE window. (I'm a complete NOOB)
To run a Python 3 program in IDLE, from the command line:
$ python3 -m idlelib -r your_script.py
For earlier Python versions, see How to start IDLE (Python editor) without using the shortcut on Windows Vista?

I am trying to run Python from VS Code. I have already activated python through the terminal. However, in the terminal selector in the lower right of the screen, I cannot find Python terminal option there:
I wish to ask how could I make Python terminal visible here so that the next time I wish to switch terminal to Python, I do not have to load a .py file but could just selecting Python terminal directly. Thank you.
Python terminals aren't really a thing. If you want to run a .py file, do $ python [filename].py or $ python3 [filename].py. If you want to just run commands, open a Python shell by doing $ python or $ python3
There is no Python terminal. If you are asking about loading Python shell you just have to type python into your terminal to load the Python shell
Using Python 3.10:
import os
os.system('notepad.exe')
Notepad launches, but if I try that with pythonw.exe Idle doesn't launch but the exit code is also 0.
Not sure why. Is it because pythonw is not an external application? How can I launch IDLE from the interpreter?
I apologize, not sure how to include code properly....
Many thanks
pythonw is not IDLE. pythonw is just another copy of python that is marked as a Windows GUI application, so it doesn't attach to your terminal session. IDLE is a separate command. Depending on where your Python installation is, you can run:
C:\Python310\Lib\idlelib\idle.bat
Or, even easier:
pythonw -m idlelib
This command runs under bash on Linux:
python file.py variables
But when I write it to the IPython console in Spyder I get:
SyntaxError: invalid syntax
Q: How can I run a python script using the IPython console in Spyder?
(Spyder maintainer here) To run a Python file in Spyder, you just need to open it in its editor and the go to the menu
Run > Run file
or press F5. That basically reads the contents of the file and executes it with exec (as it was suggested in the answer by Jeremy Hue).
If you want to pass arguments to your script, please see my answer for that here.
Your IPython console is already running Python, whereas the command python file.py in bash is basically saying 'run file.py using Python'.
Check out this solution if you want to run file.py explicitly via the IPython console

Having made as small print('Hello') in Windows Emacs, I try to run this from within Emacs, using first ^C^P to make Python interpreter, and then ^C^C to run then code. However this only says:
send: print...
But it does not run the code. How to make Windows Emacs run the code also ?
Version info:
GNU Emacs: 25.0.50.1
Python: 3.5.2
I can use python 3 in terminal fine, but I don't know how to make it so terminal will run a program that I have written in python 3.
What do i have to do to associate the .py file extension with python3.2.3 for terminal and not python2.7.1
I am using textwrangler as my text editor, but will happily use any editor if it will run, though I don't think this is my problem as idle doesn't work either and it doesn't have line numbers in it either.
Kind regards

Add a python3 hashbang to the beginning of your scripts:
#!/usr/bin/env python3
# do stuff
Then, you can make your script executable and run it:
chmod +x script.py
./script.py
try python3 yourprogram.py in your terminal.
or by adding this line on the top of our programs, this is the path to your interpreter:
#!/usr/local/bin/python3.2
