身体质量指数BMI

思路方法：难点在于同时输出国内和国际回应的的分类

#CalBMI.py;
height,weight = eval(input("请输入身高（米）和体重（公斤）【逗号隔开】:"))
bmi = weight / pow(height,2)
print("BMI的值为：{:.2f}".format(bmi))
who,nat = "",""
if bmi<18.5:
    who,nat = "偏瘦","偏瘦"
elif 18.5<=bmi<24:
    who,nat = "正常","正常"
elif 24<=bmi<25:
    who,nat = "正常","偏胖"
elif 25<=bmi<28:
    who,nat = "偏胖","偏胖"
elif 28<=bmi<30:
    who,nat = "偏胖","肥胖"  
else:
    who,nat = "肥胖","肥胖"
print("BMI指标为：国际'{0}',国内'{1}'".format(who,nat))
