How do I check whether a file exists without exceptions?

Question

How do I check if a file exists or not, without using the try statement?

Answer 1

You can write Brian's suggestion without the try:.

from contextlib import suppress

with suppress(IOError), open('filename'):
    process()

suppress is part of Python 3.4. In older releases you can quickly write your own suppress:

from contextlib import contextmanager

@contextmanager
def suppress(*exceptions):
    try:
        yield
    except exceptions:
        pass
