simplify repeated calls to `print(..., file=f)` in Python

printer.py

from functools import partial

class printer:
    def __init__(self, *args):
        self.args = args
    def __enter__(self):
        self.f = open(*self.args)
        return partial(print, file=self.f)
    def __exit__(self, *args):
        self.f.__exit__(*args)

with printer("out.txt", "w+") as p:
    p("Hello, world!")
