I can't get pythons output viewer to run - python-3.x

I just downloaded python on a new pc and now whenever I try to create a script the output viewer just closes down immediately when I launch it as a python file.
My original script was
import secrets
secrets.token_hex(32)
but it just closes down immediately. I thought that it was something with my code so I tried to just make the simple "hello world" script.
(print) "I hope this work"
and I had the same result as the first script, the output window opened up then immediately closed down.
I can get it to work using the python shell but I prefer doing all my coding using notepad++ and it would a real pain in the behind if I can't get that to work.

This is expected behavior if you run your scripts as you described, by opening them in Explorer. Your script completes execution in a terminal window, then closes immediately.
If you absolutely insist on running them on double click and still want to see your console, I suggest you create a .bat file at your python path with contents like this:
python -i %1
and them bind your double-click handler to use that file on .py extension. That way, Python will execute your file and go into CLI mode, preserving your terminal window and allowing you to type further commands.
My other guess would be that you want a console plugin to work right within Notepad++, in that case use nppexec: https://sourceforge.net/projects/npp-plugins/files/NppExec/

How to navigate from running python script in ubuntu terminal?

I am currently running a python3 script in Ubuntu server 18.04. When i type new commands into the command line it just prints the commands. My terminal window looks like this:
mitch#server:`$ cd /home/mitch/folder
mitch#server:`/folder$ python3 main.py
file running ...
text i input just shows like this
I need to keep the script running and run other commands, how do i navigate back to:
mitch#server:`
I'm new to servers/Ubuntu/commands so this may seem trivial! Thank you
So you can't "navigate" back to that, since you're technically already there, you're just running a script in your shell which is occupying your shell - think of it like you opened a program in full screen.
But you have a few options:
The most basic is to run the script in the 'background' this is a simple as adding a & to the end of your command (note that it will still send any message from the script into your terminal - if your script is programmed to send messages that is).
Another option is to use a terminal multiplex like which lets you have multiple terminals open, as well as split screen terminals and many other features. One of the more popular multiplexers is called tmux, just keep in mind that it does have a bit of a learning curve to it, but is extremely useful once you learn it.

Python VSCode: Run Main file in Python Interactive Window

This seems like a basic question, but I can't seem to find a setting/process for it.
In VSCode's Python extension, there is an option to right-click (or keyboard shortcut) in the editor and Run Current File in Python Interactive Window. This works great.
Is there a way to Run Main File in Python Interactive Window so to speak? If you are building a package/module and are making changing in a non-main file, you currently need to switch back to that main file editor tab before running it as described above.
It would be nice to link module/package files to run the main file from anywhere in the package and not have to switch files in the editor. This would make building/debugging a separate module file much faster using the Python Interactive Window. Thanks
Create a launch option that names the main python file instead of the current file and choose it in the debug/run sidebar.
You might need to set the cwd property to the correct value.
Now when you press F5 the main python file is run.

Python Screen closing when i run test.exe file

Hi all iam new to Python, I have created test.py script then i made exe using "pyinstaller --onefile SNMP_TeamDynamicCheckV1.py " , now i could see "test.exe file in "C:\Python34\Scripts\dist" path. when i run my script my screen getting closed immediately. how keep my screen After Running test.exe file. if provide with solution it would be helpful to me
I am not sure you like this, but I'll show you an idea.
If you put the code below at the end of your script, the windows will wait for 10 seconds and then close. If you want more or less time, just change the number.
import time
time.sleep(10)
I assume this happens because the resulting exe is a console application. Default behaviour of these is to close the (new) console window when done.
You can either
Run it from existing command line window to see the output,
Modify the program and add keyboard input at the end:
input('Press enter to continue')

pywinauto (or others): to emulate Ctrl+A & Ctrl+X anywhere (not only on specified app)

I'm looking for a way to generate a ctrl+A (select all), and then ctrl+x in a python script. I know how to generate this in a specific app (pywinauto and other modules do that). But I'm looking for a way to send these keys in any apps (in any field of the active windows). I want to launch the python script containing these keys anywhere (the script will be launch using a key shortcut. Details below (1))
EDIT: I'm NOT trying to copy/past in the command windows (cf. the 2 last sentences). My script send the keys in the command windows, but that's the problem I'm trying to solve...
Using python pywinauto (or Ctypes or other modules)
I tried several propositions listed here with the same result.
I thought pywinauto could do it. Following pywinauto latest documentation I tried that:
open an (any) app containing a text field (that's the active windows)
place the cursor where you want to make the select all + cut/past
run the script bellow using an shortcut (so you won't leave the active windows)
from pywinauto.keyboard import SendKeys
SendKeys('^a^x')
Result
The code only print ^A^X in the python console. It doesn't do what it's suppose to do in the field of the active window (where I placed my cursor): it doesn't select all + cut the text.
Using autohotkey:
The only way I found to simulate a real crtl+A ctrl+C is by using autohotkey (it works but it's not a python solution):
save the code bellow in my AHK script: select_copy.ahk
Send, ^a
Send, ^x
create another AHK script called shortcut.ahk where you will specify a shortcut to launch select_copy.ahk (shortcut.ahk sould run constantly in windows background (2))
!^+G:: Run select_copy.ahk , C:\Users\Me\Desktop
(meaning: when I hit ctrl+alt+shift+G run the script select_copy.ahk)
result:
It works. when I call the ahk, it select/cut things in the active windows.
A combination of both did not work
I tried to launch the select_copy.ahk from within a python script (using subprocess.call) but I ended up with the same result than pywinauto (or Ctypes): it only prints ^A^X in the consol, but doesnt select&cut. So I'm wondering if python could really do what autohotkey does.
(1) What the script will do: I will launch the script (using a shortcut key) on one or another html editor, it will cut all the text, parse its source code, make some change put back the datas in the clipbboard, and past it. I'm only missing the first part (select all + cut) and the last part (past).
(2) It's not the big deal since shortcut.ahk contains also all my other ahk shortcuts and scripts.
Your AutoHotKey script should work, and does on my machine. However, I recommend that you just have one shortcut.ahk file containing the following:
!^+G::
Send, ^a
Send, ^x
Return
...and then put this in your python file:
subprocess.call("C:\\Path\\To\\AutoHotKey.exe /r C:\\Path\\To\\shortcut.ahk")
replacing the paths with wherever the AutoHotKey executable is, and wherever the shortcut.ahk file is.
Just as a side note: !^+G:: triggers on Alt+Shift+Ctrl+G, not Shift+Ctrl+G as you wrote in your question:
(meaning: when I hit ctrl+shift+G run the script select_copy.ahk)
EDIT: Also, from the phrase in the python console in your question it seems like you're trying to select all and then cut it in CMD. This will not work at all. Instead, if you want to simply clear the console, just use the command cls (Windows only; use clear in Linux). If you want to copy the entire console output and then clear it (i.e. cut) you're gonna need something different.

python3 input using sublime text 3

I am trying to use the input feature on python for my program. I installed SublimeREPL but I still cant seem to figure out how to provide an input for my program. (coming from a complete beginner)
Using input from within an editor can be tricky. A simple solution would be to run your program from the command line. Open a terminal and change into the directory where your script user_inputs_intro.py is located and type:
python user_inputs_intro.py
Now, you will see the Tell me something: and should be able to type something that will be echoed back after you press enter.
