Suppressing print output in python3 with file parameter

Question

I have several functions that I want to set the verbosity level of. Currently, I'm handling it like so:

class Foo:
    def __init__(self, foo_stuff, verbose=True):
        self.print_file = None if verbose else open(os.devnull, 'w')

    def do_stuff(self):
        print('doing stuff', file=self.print_file)

This works, but I don't like that I never close the file self.print_file.

For cleanliness, I'd prefer not to wrap every single print function in a with open(...). I was wondering if anyone could suggest another way of doing this. For this application, I don't think the python logging module will work.

Answer 1

atexit module may help. write a cleanup function in your Foo class and register it by calling

atexit.register(function, args)

to be called before your program exits.
