height = 1.78
weight = 65

def Bmi(height,weight):
    bmi = (weight / height * height)
    if bmi < 18.5:
        print ('过轻')
    elif 18.5 <= bmi < 25:
        print ('正常')
    elif 25 <= bmi < 28:
        print ('过重')
    elif 28 <= bmi < 32:
        print ('肥胖')
    else :
        print ('严重肥胖')

Bmi(height,weight)

将bmi = (weight / height * height)中的‘height * height’

替换为‘ height**2’ 就能得到正确的答案？

x ** 2和x*x  的结果不一样么？
