垂直合并 .txt 文件的内容

Question

I would like to merge the content of specific .txt files VERTICALLY in a folder (directory) via one commant in python,

I have tried the following code but its no use (I mean it works, but the put the output is shown as one horizontal plot, and not multiple vertical lines)

import glob

read_files = glob.glob("mypath/finalR*.txt")

with open("result5.txt", "wb") as outfile:
    for f in read_files:
        with open(f, "rb") as infile:
            outfile.write(infile.read())

could you help me?

Answer 1

Couple of things to note:

1. b is for opening a file in binary mode. You don't need this since you are working with text files.
2. Since you have only a couple of files, I suggest you read all the lines into a Python list and write into the output file once.

Keeping these in mind, the solution now looks like the following:

 read_files = glob.glob("mypath/finalR*.txt") lines = [] for file in read_files: with open(file, "r") as f: lines.extend(x.strip() for x in f.readlines()) with open("result.txt", "w") as f: f.write('\\n'.join(lines))
