In theory, it is. In practice, that is the way Python code is written
because it more natural and to the point. Not just for hacked together
scripts, lots of third party modules includes code like "data =
open(filename).read()" and similar idioms.

Have you ever experienced a problem caused by not explicitly closing
your file handles?
