圖檔:

代碼如下：

import pandas as pd
import numpy as np
import matplotlib.pyplot as plt
while True:  
    height= input("輸入身高")
    weight =input("輸入體重")
    age = input("輸入年齡")
    sex = input("輸入性别")
    try:
        for i in [height,weight,age,sex]:
            if i==height:
                if type(float(i)) == float and 0<float(i)<3:
                    height = float(height)
                else:
                    print("你輸入的身高有誤，清重新輸入")
                    height= input("輸入身高")
                    height = float(height)               
            if i==weight:
                if (type(float(i))==float) and 0< float(i)<300:
                    weight=float(weight)
                else:
                    print("你輸入的體重有誤，清重新輸入")
                    weight =input("輸入體重")
                    weight=float(weight)
            if i==age:
                if type(int(i)==int) and 0 < int(i)< 100:
                    age = int(age)
                else:
                    print("你輸入的年齡有誤，清重新輸入")
                    age = input("輸入年齡")
                    age = int(age)

                    sex = input("輸入性别")       
        break           
    except:
        print("TypeError")
        
BMI =weight/(height*height)
fat= 1.2*BMI+0.23*float(age)-5.4-10.8*float(sex)
   
if sex==1:
    if fat>=0.15 and fat<=0.18:
        print("體重正常")
    elif fat<0.15:
            print("偏瘦")
    else:
            print("肥胖")

    else:
