height = 1.75
weight = 80.5

bmi = weight/(height*2)

if bmi <18.5:
    print('BMI为%d,体重过轻' % bmi)
elif bmi >= 18.5 and bmi < 25:
    print('BMI为{0:.1f},体重正常'.format(bmi))
elif bmi >= 25 and bmi < 28: 
    print('BMI为%s,体重过重'.format(bmi))
elif bmi >= 28 and bmi < 32: 
    print(f'BMI为{bmi:.1f},体重肥胖')
elif bmi >= 32 :    
     print(f'BMI为 {bmi:.1f} ,体重严重肥胖')
