How to clear Python shell ?
I am writing a module in python, I want to save it in a file. what is the best way to do it?
File -> New Window. Put your module in this new window, than save it. To run, just press F5.
Python shell does not get cleared or saved. Perhaps you are using IDLE. It's a confusing piece of software. I'd recommend you to get a real IDE, or at least a proper text editor.
Something that I do in IDLE is print "\n"*100
You can also extend Idle and map that to a key. Read Pythoninstall\lib\Idlelib\extend.txt for details

If you are just in console, you can do ( which won't work in IDLE):
import os
os.system("cls")
Just copy and paste the code into a new file (In file), and save it. To run, you can go to the run section and select "Run Module", or you can simply press F5.

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.
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/
I'm doing some engineering analysis with the help of a FEA program and Python. When the analysis ends I need to press a key to continue. But this is not a normal press any key to continue. Every code executed with the scripts stops. Like a handput debug break. Nothing runs until I press something or switch windows.
I cant use send keys and subprocesses because running code completely stops. Only solution I could come up with is to use another script in another command window with simple send keys command. This extra script is useless if computer is used or another window is active.
I'm a beginner level programmer and maybe I'm missing something simple. I guess the problem is caused by the FEA programs code but I'm not sure. So is there any way to prevent my code from stopping? Thank you for your time.
It seems that the FEA program does the windowing and you cannot do much about it. I actually automate scripting in DIANA FEA. For this program I would try something like pywinauto.
https://github.com/pywinauto/pywinauto
And call your python script from another python script.
from pywinauto import Desktop, Application
import time
app = Application().start("FEA_program.exe my_python_script.py")
while True:
time.sleep(5)
# send key presses to the app every arbitrary seconds
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.
What needs to be done?
I need to make a connection to the remote machine through UNIX, go to the shared drive, open an excel file, save it and close it. This needs to written in an script.
The file contains macros so they needs to be opened manually on daily basis, save it and close it. We plan to write a script that would run on daily basis and refresh this file automatically.
Where am i facing the issue?
Making a connection to the remote machine is done, after that i run certains commands:
1. Open the command prompt
2. cd the file path
3. Open the File
Now this is where the issue starts
How to save the file automatically?
How to close that file?
I tried using the taskill option and it almost worked but it gives out the popup of Do you want to save the file and i dont know how to provide output to that popup through command prompt.
Let me know if you have any idea on how to move ahead on this.
A bit hackish, but xdotool, a program which simulates mouse clicks and keyboard presses could be used. If Windows is being used, then see this question for tools which simulate mouse clicks and keyboard presses.
Have you tried SendKeys?
That may help.
