python - 在python中并排加入txt文件

Question

我在 txt 文件中有 2 个数据数组：

A1 A2 A3
A4 A5 A6
A7 A8 A9

和

B1 B2 B3
B4 B5 B6
B7 B8 B9

我想将它们并排组合：

A1 A2 A3 B1 B2 B3
A4 A5 A6 B4 B5 B6
A7 A8 A9 B7 B8 B9

（这些空格实际上是我的 txt 文件中的制表符）

谢谢！

Answer 1

从任一文本文件中同时读取行。连接您每次读取的行，并将结果写入一个新的文本文件。

Answer 2

像这样的东西：

>>> with open("data1.txt") as f1,open("data2.txt") as f2,open("out.txt","w") as f3:
...     for x,y in zip(f1,f2):
...          f3.write(x.strip()+" "+y.strip()+'\n')

输出：

A1 A2 A3 B1 B2 B3
A4 A5 A6 B4 B5 B6
A7 A8 A9 B7 B8 B9

Answer 3

To abstract @Ashwini's answer to any number of files:

filepaths = list_of_filepaths
with open('path/to/output') as f:
    for lines in zip(*[open(fpath for fpath in filepaths)]):
        outfile.write('\t'.join(line.strip() for line in lines) + '\n')
