Having two branches in the same if structure with the same implementation is at best duplicate code, and at worst a coding error. If the same logic is truly needed for both
instances, then they should be combined.
if 0 <= a < 10: do_the_thing() elif 10 <= a < 20: do_the_other_thing() elif 20 <= a < 50: do_the_thing() # Noncompliant; duplicates first condition else: do_the_rest()
if (0 <= a < 10) or (20 <= a < 50): do_the_thing() elif 10 <= a < 20: do_the_other_thing() else: do_the_rest()
or
if 0 <= a < 10: do_the_thing() elif 10 <= a < 20: do_the_other_thing() elif 20 <= a < 50: do_the_third_thing() else: do_the_rest()
