Python计算除法的基本代码，如何避免分母为0的情况

try:
    numerator = float(input("Enter the numerator: "))
    denominator = float(input("Enter the denominator: "))
    fraction = numerator / denominator
    print(fraction)
except ValueError:
    print("Numerator and denominator must be valid numbers!")
except ZeroDivisionError:
    print("Cannot divide by zero!")
print("Finished.")

上面是代码，如何修改避免分母为0的情况

Answer 1

在除法 fraction = numerator / denominator前加上if语句判断denominator是否为0
