&名字问题&

My friend wants a new band name for her band. She like bands that use the formula: 'The' + a noun with first letter capitalized.

dolphin -> The Dolphin

However, when a noun STARTS and ENDS with the same letter, she likes to repeat the noun twice and connect them together with the first and last letter, combined into one word like so (WITHOUT a 'The' in front):

alaska -> Alaskalaska

europe -> Europeurope

Can you write a function that takes in a noun as a string, and returns her preferred band name written as a string?

由于不清楚输入的字符是否全部小写以及输出是否要求严格「仅首字母大写」，试写了两个版本：

1. def preferred_band_name_raw(rawstr):
   
2.     if rawstr[0].lower() == rawstr[-1].lower():
   
3.         tmp = rawstr[1:] * 2
   
4.         return rawstr[0].upper() + tmp
   
5.     else:
   
6.         return 'The ' + rawstr[0].upper() + rawstr[1:]
   
7. 
   
8. def preferred_band_name(rawstr):
   
9.     if rawstr[0].lower() == rawstr[-1].lower():
   
10.         return (rawstr[0] + rawstr[1:] * 2).title()
    
11.     else:
    
12.         return 'The ' + rawstr.title()
    
13. 
    
14. print('preferred_band_name_raw:')
    
15. print(preferred_band_name_raw('Dolphin'))
    
16. print(preferred_band_name_raw('DolphiN'))
    
17. print(preferred_band_name_raw('Dolphid'))
    
18. print(preferred_band_name_raw('DolphiD'))
    
19. print('preferred_band_name:')
    
20. print(preferred_band_name('Dolphin'))
    
21. print(preferred_band_name('DolphiN'))
    
22. print(preferred_band_name('Dolphid'))
    
23. print(preferred_band_name('DolphiD'))

复制代码

输出：

1. preferred_band_name_raw:
   
2. The Dolphin
   
3. The DolphiN
   
4. Dolphidolphid
   
5. DolphiDolphiD
   
6. preferred_band_name:
   
7. The Dolphin
   
8. The Dolphin
   
9. Dolphidolphid
   
10. Dolphidolphid

手法低劣，还望大Lao指正！

2.     n = n.lower()
   
3.     if n[0]==n[-1]:
   
4.         return n[0].upper()+n[1:]*2

呐呢

1. def NewBand(str):
   
2.     str0=str.capitalize()
   
3.     if(str[0]==str[-1]):
   
4.         str0+=str[1:]
   
5.     else:
   
6.         str0='The '+str0
   
7.     print(str0)
   
8. name = input("Please input The band name:")
   
9. NewBand(name)
   

复制代码

运行结果：
====================== RESTART: F:\Python3\code\名字问题.py ======================
Please input The band name:dolphin
The Dolphin
>>>
====================== RESTART: F:\Python3\code\名字问题.py ======================
Please input The band name:alaska
Alaskalaska
>>>
====================== RESTART: F:\Python3\code\名字问题.py ======================

上面的代码可以继续精简为：

1. def NewBrandName(s):
   
2.     print (s.capitalize()+s[1:] if s[0]==s[-1] else "The "+s.capitalize())
   
3. s = input("请输入名字:")
   
4. NewBrandName(s)
