python subprocess, redirecting exit code to a file

Using subprocess run()/popen(), we are able redirect stdout and stderr to an external file. Is there any way to also redirect exit code as well?

Just read the returncode attribute of the returned object of subprocess.run, and write that to a file.

import subprocess

r = subprocess.run(["ls"])
with open("returncode.txt", "w") as f:
    f.write(str(r.returncode))
