How to redirect error output in python?

Question

linux

I have a python3 script which I am running on linux. Sometimes this script throws a bunch of errors and exceptions. I want all error and exception messages to be written to a file and the output of the script to remain clean. To do this, I do this:
myscript.py 2> errors.log
But I don't want to write "2> errors.log" every time, I want the script itself to be able to redirect the stream with errors.

Answer 1

sys.stderr = open("/.../errors.log", "a")

Answer 2

Wrap the program start in a shell script - it suggests itself in the first place.
