Python - 来自 2 个文件的行与\n

Question

我是 Python 新手。我有两个文件，其中包含我需要将 2 个文件逐行组合成一个文件的句子。

file_1.txt: 
feel my cold hands.
I love oranges. 
Mexico has a large surplus of oil.
Ink stains don't rub out.

file_2.txt: 
≥ª ¬˘ º’¿ª ¡ª ∏∏¡Æ∫¡.
∏«¸ ∫Ò«‡±‚∞° ∞≠¿ª ≥Øæ∆∞¨¥Ÿ.
∏flΩ√ƒ⁄ø°¥¬ ¥Ÿ∑Æ¿« ø©∫–¿« ºÆ¿Ø∞° ¿÷¥Ÿ.
¿◊≈© ¿⁄±π¿∫ ¥€æ∆µµ ¡ˆøˆ¡ˆ¡ˆ æ ¥¬¥Ÿ.



FINAL OUTPUT should look like: 

feel my cold hands.
≥ª ¬˘ º’¿ª ¡ª ∏∏¡Æ∫¡.

I love oranges. 
∏«¸ ∫Ò«‡±‚∞° ∞≠¿ª ≥Øæ∆∞¨¥Ÿ.

Mexico has a large surplus of oil.
∏flΩ√ƒ⁄ø°¥¬ ¥Ÿ∑Æ¿« ø©∫–¿« ºÆ¿Ø∞° ¿÷¥Ÿ.

Ink stains don't rub out.
¿◊≈© ¿⁄±π¿∫ ¥€æ∆µµ ¡ˆøˆ¡ˆ¡ˆ æ ¥¬¥Ÿ.

这是我尝试过的

filenames = ['data/data.txt', 'data/data2.txt']
with open('data/test.txt', 'w') as outfile:
    for fname in filenames:
        with open(fname) as infile:
            for line in infile:
                outfile.write(line)

这里的代码只是一个接一个地连接文件。但是，它不是逐行分割并创建\n。谢谢!!

Python concatenate text files

所以诀窍是我们想同时遍历两个文件。为此，我们可以像这样使用 zip 函数:

filenames = ['data/data.txt', 'data/data2.txt']
with open('data/test.txt', 'w') as outfile:
    with open(filenames[0]) as f1, open(filenames[1]) as f2:
        for f1_line, f2_line in zip(f1, f2):
            outfile.write(f1_line)
            outfile.write(f2_line)
            outfile.write("\n")  # add blank line between each pair
