Execute terminal commands in python3
Question:
I am on a Raspberry Pi, and I am using a program called fswebcam, which allows you to take pictures with a webcam.
~$ fswebcam image.jpg
That command if entered in terminal takes a picture and saves it to your computer, however I want to build a simple python program that can access the terminal and execute that same command as I have listed above.
I have tried to import os and use os.system('fswebcam image.jpg') But it isn’t working for me.
How can I have python execute terminal commands?
Answers:
Use the subprocess module:
import subprocess
subprocess.Popen(["fswebcam", "image.jpg"])
