How to pass variable name in subprocess command

Question

import subprocess
result = subprocess.call('"C:\\Users\\user\\Desktop\\Install Exe\\download.exe" /S norestart ', shell=True)
print(result)

This is something hardcode in the command, I want to pass this path in the variable and want variable instead of the path

Can we do this thing?

Just use

subprocess.run(["arg1", "arg2", "arg3"])

so say I wanted to move a file from "/home/myfile.txt" to "/home/data" which accepts the arguments sourcefile and destination folder I would do

subprocess.run(["mv", "/home/myfile.txt", "/home/data"])

any of these strings can be variables and the strings can be f-string formatted also

@RishiVashishtha, this answer tells you to stop using `shell=True` and instead pass a list of individual arguments. You can use a variable for any of those arguments. – Charles Duffy Dec 16 '21 at 17:47
