subprocess.call is a simpler function for running external commands. It is more concise but less flexible compared to Popen. call() is typically used when you don’t need to interact with the process directly and just want to run a command and wait for its completion.
Here’s how you can use call() for redirection:
import subprocess
# Using call as a shortcut
subprocess.call(['./my_script.sh'], stdout=open('output', 'w'))
Explanation: call() runs the command and redirects stdout to the output file. This is a simpler approach if you don’t need to handle additional process details.
