depends on the use case; in a small program that you know will only read
a few files, you can leave it to the system (especially on CPython). if
you're about to process large number of files, or you're writing files,
it's usually better to be explicit.
note that to be really safe, you should use try/finally:
f = open(filename)
try:
f.write(...)
finally:
f.close()
</F>
