In VS Code, is there any way to run a Python source line in terminal (shift+Enter), ignore leading >>>?
I heard some other editors have such functionality as one of their built-in features (e.g., IPython). In the case of VS Code, do you have any suggestions for set-ups or extensions?
I think what you mean is ti run it in interactive mode, correct me if I am wrong.
CTRL + SHIFT + T and then type
run current file in interactive window.
When you shift+Enter in your python script, VSCode deliver your line to the terminal which run python in interactive mode. It means, removing leading prompt string is not the matter of VSCode, but the terminal or python program itself.
The leading prompt string(>>> and ...) is defined in sys package. If you want to remove it, try this:

>>> import sys
>>> sys.ps1, sys.ps2 = '', ''
ps. I still can't find the way to configure this as default setting in VSCode.

I'm going through free Google Python training course. Real basic stuff. My OS is MacOS. Using MacOS Terminal. I can run python modules like hello.py.
I can run this to see my version:
% python --version
Python 3.9.12
However, this fails:
% python help(sys)
zsh: unknown file attribute: y
What do I need to change in my setup to resolve and be able to call simple help in Python?
Parentheses have a special meaning in zsh, so they must be escaped here to pass the argument as-is to Python. You can use \ in front of the parentheses (python help\(sys\)), but it's conventional to just quote the entire argument:
python 'help(sys)'
However, this still won't work (because the python command interprets it as a filename), you need to pass code via the -c flag to Python:
python -c 'help(sys)'
And that still won't work since you haven't loaded the sys package in that code. Do that, to get working code:
python -c 'import sys; help(sys)'
Konrad is right, but you are likely looking for a way to start Python interactive shell and execute statements there.

You are typing in a z shell, but you are trying to execute python code. To enter python's interactive mode, you can simply type /usr/bin/local/python3 (or python3 directly might work if things are setup correctly on your computer).
Once you do that, you should see something like

I just started learning python. I created a simple .py file using the IDLE editor and I am trying to run it from the command prompt. However, every time it keeps giving me the "SyntaxError: Invalid Syntax" message.
This is how the .py file looks when opened with notepad:
Python 3.6.2 (v3.6.2:5fd33b5, Jul 8 2017, 04:57:36) [MSC v.1900 64 bit (AMD64)] on win32
Type "copyright", "credits" or "license()" for more information.
>>> import sys
>>> print(sys.platform)
win32
>>> x="Spam!"
>>> print(x*8)
Spam!Spam!Spam!Spam!Spam!Spam!Spam!Spam!
>>> print(2**100)
1267650600228229401496703205376
>>>
And this is what I type in the cmd:
C:\code\script1.py
Assistance would be appreciated.
That's not a Python program, it's the log of an interactive (command prompt) session.
Instead, try entering the following in any text editor (e.g. notepad, notepad++), save it as C:\code\script2.py and then run it as you did:
import sys
print(sys.platform)
x="Spam!"
print(x*8)
print(2**100)
[EDIT]
If you want to use Idle for this, click [File][New] to create a Python source code file, type in the above, save it and then run it as you did.
[EDIT2]
Idle is and example of an Interactive Development Environment (IDE). Since you're new to programming: IDE's tend to obscure what's going on, although Idle isn't a severe case of this. So using a separate editor and running from the command line as you did is actually a good way to familiarize yourself with what's going on under the hood. This will pay off in many ways in the long run.
As said before; This is not a python file...

That's the shell (which you get if you just type: python) where you can type commands like:
fruits = ["apple", "banana", "cherry"]
for x in fruits:
print(x)
and this will instantly execute...
What you need to to is go on and create a script.py file, write your stuff in there and then execute it as: python script.py

I usually use sublime to run my code, but when I try to use the interpreter (both in cmd and powershell) it opens python and then immediately exits without any input from me.
eg:
PS C:\Users\Lahoa\Documents> python
Python 2.7.13 (v2.7.13:a06454b1afa1, Dec 17 2016, 20:53:40) [MSC v.1500 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
PS C:\Users\Lahoa\Documents>
As you can see it opens python(successfully), then exits without me being able to do anything. Has anyone seen this before? When I google I only find help regarding running scripts that close automatically on finish...
Thank you for any input
I found a solution. We have a script that adds various paths for various extra packages at my work. I found an error in one of the imports, which caused python to fail but wasnt giving an error message due to a try statement in the script.
I'm a newbie programmer so I'll do my best to clearly ask my question. I'm running Python scripts in Mac 10.6.5 and now trying to write and save to a text file (following instructions in HeadsUp Python book). Whenever I hit function+F5 (as instructed) I get the same "invalid syntax" error and Idle highlights the "1" in "Python 3.1.3" of the header. Here's the header to which I'm referring:
Python 3.1.3 (r313:86882M, Nov 30 2010, 09:55:56) [GCC 4.0.1 (Apple Inc. build 5494)] on darwin Type "copyright", "credits" or "license()" for more information.
Extremely frustrating. I've checked and rechecked the code but this doesn't seem to be code related because the "syntax error" is in regards to the header text that posts in every Idle/Python session. Help anyone?
... and Idle highlights the "1" in "Python 3.1.3" of the header ...
Standalone Python scripts used to contain a "header", but that would be just
#!/usr/bin/env python
or, depending on the name of the interpreter maybe
#!/usr/bin/env python3.1
Not sure I understand your question, though.
you are writing your script in the wrong IDLE window ! when starting IDLE, it opens 2 windows: one for writing a script and another one with an interactive python shell. executing the content of the interactive python shell makes no sense.
#squashua: I have the same issue when I try to run the code either in IDLE or Ubuntu terminal.
Python 3.5.1 (v3.5.1:37a07cee5969, Dec 6 2015, 01:54:25)
it highlights "5" as syntax error.
