Is it possible to have an optional with/as statement in python?

Question

Instead of this:

FILE = open(f)
do_something(FILE)
FILE.close()

it\'s better to use this:

with open(f) as FILE:
    do_some         


        

Answer 1

something like:

if file:      #it checks for None,false values no need of "if file is None"
    with open(file) as FILE:
        do_something(FILE)
else:
    FILE=None
