將這5個文件夾合並到sdf.txt文件中

import re

from envs.django.Lib import os

if __name__ == ‘__main__‘:

    f1 = open(‘d:/englishbook/sdf.txt‘, ‘a+‘, encoding=‘UTF-8‘)
    path = ‘D:\englishbook‘
    filelist = os.listdir(path)
    print(filelist)
    for i in filelist:
        an = re.search(‘^[Tech\d\.txt]+$‘, str(i))
        print(i)
        print(an)
        if an:
            with open(‘d:/englishbook/‘+str(i), ‘a+‘, encoding=‘UTF-8‘) as file1:
                print(‘d:/englishbook/‘+str(i))
                file1 = open(‘d:/englishbook/‘+str(i), ‘a+‘, encoding=‘UTF-8‘)
                file1.seek(0)
                contents = file1.read()
                f1.write(contents)

python讀取目錄下的相似文件進行合並
