I searched on stack overflow but I did’nt find a correct answer. I use subprocess popen to call and run an entire python script and it works fine, like that : subprocess.Popen([‘python3’, ‘/home/pc/Dossier/Dossier2/Nom.py’], ) But in my system I want to modify a variable in the script Nom.py when I call it with subprocess popen. I heard about inputs parameters

‘pdflatex’ not found in subprocess within a bundled PyInstaller APP
I am attempting to create a macOS standalone app from a PyQt5 GUI using PyInstaller. All works apart from automatically generating a PDF from a TEX file using the pdflatex module (in conjunction with Pylatex). Both the pylatex and pdflatex modules require calling the subprocess module, which is done as following: Where args=[‘pdflatex’, ‘-output-directory=/Users/Desktop’, ‘-interaction-mode=batchmode’, ‘-jobname=test’] This however does not
Why is C++ getline() non-blocking when program is called from python subprocess?
I have a C++ program that waits for some text input with getline(), and it works well from the command line. However, I would like to call it from Python – send some text, get the output, and have it wait for more input. I tried with subprocess, but it seems that getline() in this case doesn’t wait for input
Different results when running C program from Python Subprocess vs in Bash
I’ve got a string/argument that I’d like to pass to a C program. It’s a string format exploit. However, there seems to be different behaviours exhibited if I call the C program from Python by doing versus The difference is that the string exploit attack works as expected when calling the script via subprocess, but not when I call it
Simultaneously map video and data streams to one subprocess pipeline in real-time
I need to process the video stream and the klvdata streams simultaneously in real-time in OpenCV/Python. I’m using FFMPEG to read the file or stream as OpenCV does not retain the klvdata. I pass the data to OpenCV with the subprocess module. My problem is I cannot figure out how to map both the video and klvdata to the same
Python. Calling openssl.exe in Windows
I have a Python script that needs to call openssl.exe in Windows. Here’s the script: If I uncomment the “os.startfile” line, I get a file not found error. That makes sense. os.startfile can’t handle arguments (is that correct?) If I uncomment the subprocess.Popen line, openssl starts, performs as it should, then hangs. openssl.exe process never exits, and so the script
Python subprocess returning exception
I have the following code that has been working until recently: it calls the opt_module_v3.py and returns messages as the child process runs. When I run the main code, I’m getting the following exception: Like I mentioned, this code was working before but I might have stuffed up since I’ve been working on improvements. Any clues on what could be
Python subprocess Popen periodic callback
I am running an HPC simulation on amazon AWS with spot instances. Spot instances can be terminated with 2 minutes notice by AWS. In order to check for termination you need to exectute curl on a spefiic URL every 5 seconds. It is a simple request that returns a json with the termination time, if AWS have initiated the termination
Is it possible to pass data other than string or list as argument for a subprocess in python?
I can start a sub-process with a list as arguments for example like this: My question is, if it is possible to pass bigger amounts of data to the sub-process? For example, if I have loaded a bunch of images and want to pass them directly as numpy arrays without having to store them to file and pass the paths
How do I pause other processes when user input / confirmation is required Subprocess Python
If I have a script (process run.py) that will run 3 subprocesses A.py, B.py, C.py (3 scripts called at same time through process run.py). The operation is fine. However say in b.py i have a line such as (pref) How can i get subprocess of A.py and c.py to wait/pause for 5seconds, in order for user to enter y or
