在python中合并目录的特定文件

Question

我有一个目录 C:/newdir/ 它包含以下文件名：

s1_student1_file
t1_teacher2_file
hab_parent5_file
y1_professor_file 
bsa_assistant2_file
t1_student_file
nas_officer_file
ee1_newguy15_file
ee1_professor15_file
f1_student8_file

我想将 s1_student1_file、t1_teacher2_file、t1_student_file、y1_professor_file、ee1_newguy15_file、f1_student8_file 和 ee1_professor15_file 的内容合并到一个名为 all_file 的新文件中，并从我拥有的目录中删除已合并的文件为此编写一个python代码，但不知道如何。

Answer 1

您可以使用glob 列出选定文件夹中所有选定的文本文件。然后，您可以使用 for 循环遍历所有文本文件并将内容写入另一个文件：

from glob import glob

with open('all_file.txt','a') as f:
    for file in glob('s1*')+glob('t1*')+glob('y1*')+glob('ee1*'):
        with open(file+'txt','r') as r:
            f.write(r.read())

---

之后删除文件：

from glob import glob
import os
with open('all_file.txt','a') as f:
    for file in glob('s1*')+glob('t1*')+glob('y1*')+glob('ee1*'):
        with open(file,'r') as r:
            f.write(r.read())
        os.remove(file)

Answer 2

导入 shutil 和 pathlib 库

您可以使用此命令安装库 -

pip install shutil

pip 安装路径库

Python 实现

import shutil 
from pathlib import Path 

firstfile = Path(r'C:\Users\Sohom\Desktop\A.txt') 
secondfile = Path(r'C:\Users\Sohom\Desktop\B.txt') 

newfile = input("Enter the name of the new file: ") 
print() 
print("The merged content of the 2 files will be in", newfile) 

with open(newfile, "wb") as wfd: 

for f in [firstfile, secondfile]: 
    with open(f, "rb") as fd: 
        shutil.copyfileobj(fd, wfd, 1024 * 1024 * 10) 

  print("\nThe content is merged successfully.!") 
 print("Do you want to view it ? (y / n): ") 

 check = input() 
 if check == 'n': 
exit() 
else: 
print() 
c = open(newfile, "r") 
print(c.read()) 
c.close()
