Question

input1，input2，output是制表符分隔的txt文件。

如果input1是

a b c
1 2 3

和input2是

e r t

然后我希望输出

a b c
1 2 3
e r t

我试图通过学习Python concatenate text files

来使用python连接文件

我试过

filenames = ['input1.txt', 'input2.txt']
with open('output.txt', 'w') as outfile:
    for fname in filenames:
        with open(fname) as infile:
            for line in infile:
                outfile.write(line)

然后尝试

filenames = ['input1.txt', 'input2.txt']
import fileinput
    with open('output.txt', 'w') as fout:
    for line in fileinput.input(filenames):
        fout.write(line)

但是这两个代码都是水平连接文件，而不是垂直连接。

代码创建了这个：

a b c
1 2 3e r t

Answer 1

输入文件的问题是，最后一行不是由换行符终止的。所以你必须手动添加它：

filenames = ['input1.txt', 'input2.txt']
with open('output.txt', 'w') as outfile:
    for fname in filenames:
        with open(fname) as infile:
            outfile.write(infile.read().rstrip() + '\n')

Answer 2

您需要使用\n换行。请尝试以下代码示例

filenames = ['input1.txt', 'input2.txt']
with open('output.txt', 'w') as outfile:
    for fname in filenames:
        with open(fname) as infile:
            for line in infile:
                outfile.write(line)
        outfile.write("\n")

垂直连接制表符分隔的txt文件
