To Steven's example, the ternary statement is a nice idiom when it emphasizes the most common results: wait_time = 10 if parking_space_close_by else expected_wait_time_in_congested_area() Or: qoutient = m / n if n else None In languages like Ruby/Perl the inverted if statement is also a useful idiom to emphasize concisely that code is exceptional in nature: def quotient(m, n) # guard code return None if n == 0 # happy path return m / n end Or: raise 'Armegeddon' if locusts_flying() useful_intelligible_happy_path_code_here() -- http://mail.python.org/mailman/listinfo/python-list
