Python Flushing and Already Closed File

How do I add a check to avoid flushing a file f with f.flush() when some function has already done f.close()?

I can't seem to figure out how to do so :/

You can use try ...except for this purpose i guess

Any operation which requires that the file be open will raise a ValueError after the file has been closed

OR use fileobj.closed property and if it True then don't do flush

file.closed bool indicating the current state of the file object. This is a read-only attribute; the close() method changes the value. It may not be available on all file-like objects.
