寫列表的列表文件每件

Question

file = open("myfile.txt","w") 
    aList = [["Hello","1","2"],["Hello","3","4"],["Hello","5","6"]] 

    for element in aList: 
     file.writelines("\n".join(element)) 

方式的新生產線弄出來的文本文件：

Hello 
1 
2Hello 
3 
4Hello 
5 
6 

他們的方式我想它出來的文本文件：

Hello 
1 
2 
Hello 
3 
4 
Hello 
5 
6 

我在循環中做了什麼錯誤，我該如何解決它？

Answer 1

只需添加一個新的生產線每element後：

for element in aList: 
    file.writelines("\n".join(element)) 
    file.write("\n") 

Answer 2

import itertools 
aList = [["Hello","1","2"],["Hello","3","4"],["Hello","5","6"]] 
with open('myfile.txt', 'w') as outfile: 
    for e in itertools.chain.from_iterable(aList): 
     outfile.write(e+'\n')
