Using the Python programming language, the histoenzymatic activity of the skin glands of male and female Norway and black rats was compared, which should be considered in the marking and social behavior of these rodents. Four arrays of digital analogs (24 parameters in each array) containing data on acid phosphatase, alkaline phosphatase, adenosine triphosphatase, and peroxidase were generated for comparison, and whose histoenzymatic activity was studied for skin glands of the nape, the mouth corners, upper eyelids, anal area, and soles of the paws (eccrine and sebaceous glands). The following results have been determined for each variant of the comparison between species and sexes: (1) for the system "male Norway rats-male black rats", it was shown that in four cases (16.7%), the histoenzymatic activity of the skin glands prevailed in male black rats, the dominance of male Norway rats amounted to eleven cases (45.8%), and the equality of the histoenzymatic activity of the skin glands between the two species was revealed in nine cases (37.5%); (2) for the system "male Norway rats-female black rats", it was shown that in five cases (20.8%), the histoenzymatic activity of the skin glands prevailed in female black rats, the dominance of male Norway rats amounted to twelve cases (50.0%), and the equality of the histoenzymatic activity of the skin glands between the two species was revealed in seven cases (29.2%); (3) for the system "female Norway rats-male black rats", it was shown that in five cases (20.8%), the histoenzymatic activity of the skin glands prevailed in male black rats, the dominance of female Norway rats amounted to ten cases (41.7%), and the equality of the histoenzymatic activity of the skin glands between the two species was revealed in nine cases (37.5%); (4) for the system "female Norway rats-female black rats", it was shown that in three cases (12.5%), the histoenzymatic activity of the skin glands prevailed in female black rats, the dominance of female Norway rats amounted to eight cases (33.3%), and the equality of the histoenzymatic activity of the skin glands between the two species was revealed in thirteen cases (54.2%). In all four interaction systems, the dominance of Norway rats over black rats in skin glands histochemical activity was established.
