如何在此模板代码中避免关于除零的警告？

if denominator == 0:
    print("Error: Division by zero")
else:
    result = numerator / denominator

try:
    result = numerator / denominator
except ZeroDivisionError:
    print("Error: Division by zero")

import math

result = numerator / denominator
if math.isnan(result):
    print("Error: Division by zero")

result = numerator / denominator if denominator != 0 else "Error: Division by zero"
