Lisp and Scheme programmers love that style. You can tell by the
number of parentheses
. In Python people usually use an
intermediate variable to break things up a bit but the amount of
acceptable nesting is a matter of personal style.
I'd say it's fine but breaking up the statement once or twice is a
good idea just because if one of the function calls in this nested
thing throws an exception, a smaller statement with fewer calls makes
for a far more readable traceback. And I hope that this whole
statement all lives inside of a method in the same x class, or is a
higher-level class that makes use of this behavior? If not, you may
want to consider doing so.
class X(object):
@property
def todays_filepattern(self):
return self.match_filename(
self.determine_filename_pattern(
datetime.datetime.now()))
def validate_todays_files(self):
return self.validate_output(self.find_text
(self.todays_filepattern))
