將字符串分割與蟒蛇

Question

定義的長度比方說，我有一個字符串..

lyrics = "Never gonna give you up Never gonna let you down Never gonna run around and desert you Never gonna make you cry Never gonna say goodbye Never gonna tell a lie and hurt you" 

我只希望在一個行顯示23個字符：

Never gonna give you up 
Never gonna let you dow 
n Never gonna run aroun 
d and desert you Never 
gonna make you cry Neve 
r gonna say goodbye Nev 
er gonna tell a lie and 
hurt you 

（希望我沒有」 t搞砸了，讓我們假裝每行有24個字符，我很困，我甚至不能算）

什麼是最好的方式去做這件事？

Answer 1

通過re.findall函數。

>>> import re 
>>> lyrics = "Never gonna give you up Never gonna let you down Never gonna run around and desert you Never gonna make you cry Never gonna say goodbye Never gonna tell a lie and hurt you" 
>>> for i in re.findall(r'.{1,23}', lyrics): 
    print i 


Never gonna give you up 
Never gonna let you do 
wn Never gonna run arou 
nd and desert you Never 
gonna make you cry Nev 
er gonna say goodbye Ne 
ver gonna tell a lie an 
d hurt you
