又学完一小课时了（撒花撒花！★,°:.☆(￣▽￣)/$:.°★ 。 话说这题练习题好绕啊(╯‵□′)╯︵┻━┻ 但是终于做完了（捂脸

# -*- coding: utf-8 -*-

height = 1.75
weight = 80.5
bmi = height*height
bmi = weight/bmi
if bmi < 18.5:
    print('过轻')
elif bmi < 25:
    print('正常')
elif bmi < 28:
    print('过重')
elif bmi < 32:
    print('肥胖')
else:
    print('严重肥胖')
pass

应该是这样的没错吧.....((/- -)/
