#1 Created at ... [Delete] [Delete and Lock User] 
w=float(input('w='))

h=float(input('h='))

bmi=w/(h*h)

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')

我觉得elif不需要写大于多少，之所以执行本行elif说明上面的不符合上面语句的条件

按你的思路，最好这样写：

if bmi <= 18.5: elif bmi <= 25:    elif bmi <= 32: else:
