如何將列表更改爲具有元組的列表？

Question

從句子創建列表是我想要做的。首先，我做了什麼正在協調這句話，data = "In many countries food manufacturers are required by"列出像

lines = data.split(' ') 

，並得到

['In','many','countries','food','manufacturers','are','required','by'] 

然後，我想改變這種形式

([('In','many'),('countries','food'),('manufacturers','are'),('required','by')]) 

我應該如何下一步呢？ 如果您詳細教授我，我將不勝感激。

Answer 1

d=[(lines[i],lines[i+1]) for i in range(0,len(lines)-1,2)] 
print d 

Answer 2

data = "In many countries food manufacturers are required by" 
lines = data.split(' ') 
print([(lines[i], lines[i+1]) for i in range(0, len(lines)-1, 2)])
