setting STDOUT and/or STDERR

[Gribouillis]

i want to have this more integrated so that the redirection is done by the script itself and minimize the number of files

The more pythonic way could be to use @DeaD_EyE 's suggestion plus subprocess.check_output() or Popen.communicate(). Here is a script

# myscript.py
from contextlib import redirect_stdout, redirect_stderr
from pathlib import Path
import subprocess as sp
import sys


def main():
    # print our args
    print(sys.argv)

    # run some command which creates output
    data = sp.check_output(['date'], stderr=sp.STDOUT, encoding='utf8')
    print(data, end='')

with Path("/tmp/bigscript.log").open("w") as ofile:
    with redirect_stdout(ofile), redirect_stderr(ofile):
        main()

Output:
λ cat /tmp/bigscript.log
['paillasse/pf/myscript.py']
