this is my code it works perfectly fine until i put it grader it says: PYTHON ONLY

Test Failed: 'Traceback (most recent call last): File "means.py", line 19, in  stdio.write(\'geometric mean = \' + str(10 **(gm))) ZeroDivisionError: integer division or modulo by zero' != 'geometric mean = 2.605171, harmonic mean = 2.189781'
