Most pythonic way to delete a file which may not exist

Question

I want to delete the file filename if it exists. Is it proper to say

if os.path.exists(filename):
    os.remove(filename)

Is

Answer 1

I prefer to suppress an exception rather than checking for the file's existence, to avoid a TOCTTOU bug. Matt's answer is a good example of this, but we can simplify it slightly under Python 3, using contextlib.suppress():

import contextlib

with contextlib.suppress(FileNotFoundError):
    os.remove(filename)

If filename is a pathlib.Path object instead of a string, we can call its .unlink() method instead of using os.remove(). In my experience, Path objects are more useful than strings for filesystem manipulation.

Since everything in this answer is exclusive to Python 3, it provides yet another reason to upgrade.
