Something wrong with mission "Shooting Range"

When I was trying to do this mission something strange began to happen with tester. Test Extra nr 9 write me that my function returned -1 and right solution is 0. This is shot((2,10),(10,2),(10,10),(3,10)) But I launched solution in Pycharm and I see score: 0. Even when I write in code command print(shot((2,10),(10,2),(10,10),(3,10))) and I click on the button "Run" I see score 0. Does anyone know why this might be happening?
