文本文件(.txt文件)与python中的列表的串联? [英] Concatenation of Text Files (.txt files) with list in python?

问题描述

假设我有两个文本文件1.txt和2.txt

Suppose I am having two text files 1.txt and 2.txt

1.txt的内容为:

['Hi', 'I', 'am']

和

2.txt的内容为:

['a', 'boy']

如何以相同的方式高效地将它们连接起来并将其写入新文件，例如3.txt，它应该如下所示:

How to join the same and write the same into a new file in time efficient manner, say 3.txt, which should look like this:

['Hi', 'I', 'am', 'a', 'boy']

我尝试过:

import os

file_list = os.listdir("path")
with open('out.txt', 'a+') as outfile:
   for fname in file_list:
       with open(fname) as infile:
          outfile.write(infile.read())

推荐答案

您可以尝试以下方法:

inputText = []
for file in ['1.txt','2.txt']:
    with open(file,'r') as file:
        inputText.extend(file.readlines()+['\n'])
with open ('3.txt','w') as output:
    for line in inputText:
        output.write(line)

或

with open ('3.txt','w') as output:
    for file in ['1.txt','2.txt']:
        with open(file,'r') as file:
            for line in file:
                output.write(line)
            output.write('\n')

编辑为您的评论:

import re
inputList = []
for file in ['1.txt','2.txt']:
    with open(file,'r') as infile:
        for line in infile:
            inputList.extend(re.sub('[^A-Za-z0-9,]+', '', line).split(","))
print(inputList)
with open('3.txt','w') as outfile:
    for line in inputList:
        outfile.write(line + '\n')
