why the same powershell command run on the powershell console but not using os.system?

I would like to include a command to create a 7zip archive withinin a Python script. Since I am working on Windows, I need to pass the command to the powershell console. I am planning to do it with os.system (I am aware that this is not the best way to do it and that I should use subprocess, but I really just need a quick fix and it would not be time effective for me to learn to use a new module in this context).
The following command works if run from the powershell console
&'C:\\Program Files\\7-Zip\\7z' a -mx=0 X:/myarch.zip X:/myarch
So I recreate the same string within python like this:
cmdl = r"&'C:\\Program Files\\7-Zip\\7z' a -mx=0 X:/myarch.zip X:/myarch"
The string is interpreted as follow:
"&'C:\\\\Program Files\\\\7-Zip\\\\7z' a -mx=0 X:/myarch.zip X:/myarch"
Now, if I copy-paste the above string within the powershell console, it runs without problems. However, if I run it within python using os.system(cmdl) I got the following error
"The filename, directory name, or volume label syntax is incorrect"
Why is this the case and how can I fix this issue ?

os.system is meant for executing cmd commands, cmd commands can be ran in powershell maybe after all powershell is a bit advanced but I'm sure that you can't run a cmd command in powershell, henceforth your code is not working.
However a creative solution for executing a powershell command from python(not using python) would be to write your command into a .ps file(powershell script)and then run it using os.startfile()(use this code: os.startfile("script.ps"))

vscode python no output

print("hello")
Whatever I write in the python file, it only gives the current file path. How could I fix it?
The default interactive shell is now zsh.
To update your account to use zsh, please run `chsh -s /bin/zsh`.

I just ran this program in VS Code and it worked fine.
Just right click and select 'Run Python file in terminal' options. It should work!

How are you running the file? You typically have to set up an environment. If you want to just run a single python file and see the output in the integrated terminal, try right-clicking the editor, and clicking Run Python File in Terminal.

Check the terminal.integrated.inheritEnv setting. I'm on ubuntu and had it set to false/unchecked. Toggling to true/checked brought back terminal functionality.

Run Python in VSCode in python shell like IDLE

I am well aware of the thread How to execute Python code from within Visual Studio Code
But none of them shows how to get the >>> python shell running with the file imported. Cuz I would like to call functions separately.
I understand that I can get the python shell going by simply typling python in the terminal but the functions in the python file have to manually imported everytime.
Is there a way to run files in VSCode like in IDLE?

you can run the file in an interactive mode in VSC code terminal by using the parameter -i :
python -i py_file.py

Install the Python Extension, then press Ctrl+Shift+P (Command+Shift+P) and type Python: Start REPL. Click the command, and you'll get an interactive Python console.

Assuming you have the official Python extension installed, you can search the command list (Ctrl+Shift+P) for "Python interactive" and you'll see several options that allow to do different variations of this:

Not sure if this was figured out or not, but I was having a similar question. How to simply use something like IDLE (the known '>>>' shell prompt) inside VSCodesee w/o chasing down plugins and their settings? I noticed that no answer was marked confirmed and although insightful, not what I was looking for.
I use Mac and while trying different things to address this, I found that by using/copying the path in the Python Launcher settings I got what I was looking for. Then, I validated the equivalent for Windows. Please see below.
Windows:
If you are using Windows, from your Terminal pane/window in VSCode, enter the path to your python.exe, including the executable name. It is located within the "User > AppData" directory.
For example: C:\Users\YOUR_USER_ID\AppData\Local\Programs\Python\Python310\python.exe
Note that AppData is a hidden folder, so may have to change your view settings in Explorer to show Hidden Items.
MAC:
If you are using MAC, from your Terminal pane/window in VSCode, enter the path to your interpreter
For example: /usr/local/bin/python3
Note: You can also do this directly from a CMD, PowerShell or a Terminal(Mac) window without having to launch IDLE, VSCode or any other coding/scripting app.

To build on the answer already provided, you can automatically run in interactive mode by changing your settings:
Go under File>Preferences>Settings. Search for "arguments" in the search bar. Then under "Python › Terminal: Launch Args", click on the link "Edit in settings.json".
Once settings.json is open, add "-i" with the quotation marks. It should look something like that:
{
"workbench.colorTheme": "Default High Contrast",
"terminal.integrated.localEchoEnabled": "off",
"terminal.integrated.shellIntegration.enabled": false,
"python.terminal.launchArgs": [
"-i"
]
}
Now, it will pass the argument -i every time you run.

How do i run python file in cmd from vscode

I have a python program which prints long outputs. When i try to run that file in vscode, its interactive window isn't enough to view full output. So is there any way to run python file in cmd from VSCODE?

If you are running windows, VSCode uses Powershell as your terminal by default. If you want to use the command prompt instead, hit ctrl+shift+p, type Shell into the command pallet, select Terminal: Select Default Shell, and change it to Command Prompt. I am not sure this will fix your problem as I think Powershell should display just as much output as the CMD, but if you want to try switching terminals, that will do it. Another option is to try to run it natively in CMD or Powershell, rather than using the VSCode integrated terminal. That might be better if changing terminals doesn't help.

As #Jeremiah said, you can also just run your script with the Cmd prompt, without using vs code. Let's say you have the file 'test1.py' saved as C:\Users\bcubrich\Documents\test1.py, and your python env .exe is saved in C:\python27\ArcGIS10.5\python.exe. I just wrote script that had this in it:
print('worked')
Then just input this into the Cmd prompt
C:\python27\ArcGIS10.5\python.exe C:\Users\bcubrich\Documents\test1.py
And it printed
worked
to the console.

using bash commands in python on mac: error 127

I am using am using Python 2.7 on MacOS and want to use a bash command within a python script.
command = "someProgram --option1 value 1 --option2 value 2"
I had to include the path of this program in my bash_profile in order to run it. I tested so far:
os.system(command)
and
subprocess.check_call(command.split(" "),shell=True)
Neither worked. The latter threw error 127 and the first one only returned 32512. A google search told me that this occurs when the command is not known.
If I now start this command within the terminal everything works perfectly fine.
Do I have to include something such that python can find this command? Why is this behavior?

With shell=True the cmd needs to be a string.
subprocess.check_call(command, shell=True)
where command is of type str

Thanks for your help. The final solution is kind of stupid. I started spyder via the anaconda GUI. If I do so the above code does not work.
If I run this directly via the console or start spyder via the console everything is fine. It seems that the bash_profile is not loaded when spyder is loaded but requires the console to do so
