怎么样？请高手多多指点。

感觉if语句写的太多了，不过看着很清楚明了，python的话，写个嵌套字典或者列表之类的把界定条件写进去，然后根据输入的数值可以很简单的到字典中去查询对应的结果，应该可以很简短的实现相同功能，在代码量上应该至少能缩短一半吧

这是检测体重的代码(单位：kg)，花了不少时间哦！

哦………………………………………………………………………………………………………………………………

单个函数不要超过50行。

每个if后面的东西基本都是重复的，可以单独写一个，然后用，这样是否会好些？

1. import sys
   
2. input_hint = ["How old are you?", "How weight are you?"]
   
3. age = int(input(input_hint[0]))
   
4. output_hint = ["You are too thin!", "Your weight is very good!", "You are too fat!"]
   
5. W = [[3, 11], [9,14], [], [], [], [], [], [], [], [], []] # 补全这里的代码
   
6. if age < 11:
   
7.     weight = int(input(input_hint[1]))
   
8.     if weight < W[weight][0]:
   
9.         print(output_hint[0])
   
10.     elif weight <= W[weight][1]:
    
11.         print(output_hint[1])
    
12.     else:
    
13.         print(output_hint[2])
    
14. 
    
15. else:
    
16.     print('How body mass index are you?')
    
17.     BMI = int(sys.stdin.readline())
    
18.     if BMI >= 18 and BMI <= 25:
    
19.         print('Your weight is very good!')
    
20.     elif BMI > 25 and BMI <= 30:
    
21.         print('You are little heavy!')
    
22.     elif BMI > 30 and BMI <= 35:
    
23.         print('You are some heavy!')
    
24.     elif BMI > 35 and BMI <= 40:
    
25.         print('You are very heavy!')
    
26.     elif BMI > 40:
    
27.         print('You are special emphasis!')
    
28.     else:
    
29.         print('You are special light!')
