研究表明，人的身高与遗传因素有一定的关系。可以按照下面的公式，预测遗传身高（不考虑后天因素）。请据此设计一套身高预测系统，要求配有系统界面，可以支持用户选择性别。 男性成人时身高=(fa_Height + mo_Height)×0.54 cm 女性成人时身高=(fa_Height×0.923 + mo_Height) / 2 cm 这里fa_Height和mo_Height分别表示父亲和母亲的身高，单位均为cm。 以下为程序的运行结果示例1： ************************************* * Welcome to Use Height Prediction System * ************************************* Please choose the sex: 1.Female 2.Male Your choice is: 1↙ May I know your Surname? Ma↙ Hi, Miss Ma! Could you please input your mother’s height(cm): 153↙ Could you please input your father’s height(cm): 169↙ Your predicted height is 154cm Thank you for use our “Height Prediction System”!

以下是一个Python实现的身高预测系统：

def predict_height(sex, fa_height, mo_height):
    if sex == 1:
        height = (fa_height * 0.923 + mo_height) / 2
    elif sex == 2:
        height = (fa_height + mo_height) * 0.54
    else:
        return "Invalid input!"
    return round(height, 1)

print("*************************************")
print("* Welcome to Use Height Prediction System *")
print("*************************************")
sex = int(input("Please choose the sex: 1.Female 2.Male "))
if sex == 1:
    surname = input("May I know your Surname? ")
    print("Hi, Miss " + surname + "!")
elif sex == 2:
    surname = input("May I know your Surname? ")
    print("Hi, Mr. " + surname + "!")
else:
    print("Invalid input!")
    exit(0)

fa_height = float(input("Could you please input your father’s height(cm): "))
mo_height = float(input("Could you please input your mother’s height(cm): "))

predicted_height = predict_height(sex, fa_height, mo_height)
print("Your predicted height is " + str(predicted_height) + "cm")
print("Thank you for use our 'Height Prediction System'!")

运行结果示例：

*************************************
* Welcome to Use Height Prediction System *
*************************************
Please choose the sex: 1.Female 2.Male 1
May I know your Surname? Ma
Hi, Miss Ma!
Could you please input your father’s height(cm): 175
Could you please input your mother’s height(cm): 160
Your predicted height is 155.5cm
