Save console output to text file (like a log)

[snippsat]

An example using logging and catch subprocess output.
Using logzero simplify logging,as don't have to write all that boilerplate logging code.

import subprocess
import logzero
from logzero import logger

# 3 rotations, each with a maximum filesize of 1MB:
logzero.logfile("logfile.log", maxBytes=1e6, backupCount=3, disableStderrLogger=True)

out = subprocess.run(['ping', 'google.com'], capture_output=True)
output = out.stdout.decode()
logger.info(output)

So now output only goes to logfile,disableStderrLogger=True False if want output also in console.

Output:
[I 190602 20:45:39 log_zero:10]
