Both would be confusing/inconsistent behavior (trying something in command line and then getting something else in Python).<br>

</div>I don't think that isatty() should be the sole determining factor. I'd<br>
rather see it used to select a default format but to allow the choice<br>
to be overridden.<br>
<br>
E.g. you might want the "pretty" format to still be used if the output<br>
is piped through more, less, pr, etc, but piping will result in stdout<br>
being a pipe rather than a tty.<br>
