How to handle both `with open(…)` and `sys.stdout` nicely?

Question

Often I need to output data either to file or, if file is not specified, to stdout. I use the following snippet:

if target:
    with open(target, \'w\') as h         


        

Answer 1

if (out != sys.stdout):
    with open(out, 'wb') as f:
        f.write(data)
else:
    out.write(data)

Slight improvement in some cases.
