遍历一个文件夹,把里面所有 txt 文件里的 [] 里的朗读时间删除,也就是替换为空。
- 1 import os
- 2 import re
- 3 import shutil
- 4 #os文件操作,re正则,shutil复制粘贴
- 5 path1 = r"" #脚本
- 6 path2 = r"" #mp3
- 7
- 8 #for root1, dirs1, files1 in os.walk(path1): #三个参数:分别返回1.父目录 2.所有文件夹名字(不含路径) 3.所有文件名字
- 9 # for root2, dirs2, files2 in os.walk(path2):
- 10 # for i in range(0, len(files2)):
- 11 # num, other = files2[i].split('_', 1)
- 12 # num_root = os.path.join(root2, files2[i])
- 13 # #print (num)
- 14 # #C:\Users\VideoEditor\Desktop\301_test\1_一单元\1_《为人民服务》\1_预习\1_音画课文
- 15 # num2 = r'\\\d_.*?单元\\%s_.*?\\1_预习\\1_音画课文$' %num#这个地方好像是有贪婪匹配,加了"单元"后可用
- 16 # for root1, dirs1, files1 in os.walk(path1):
- 17 # if re.findall(num2, root1):
- 18 # #shutil.copy(num_root, root1)
- 19 # shutil.copy(num_root, root1+'\\' + '录音.mp3')
- 20 # print("导入成功!")
- 21 path = r"C:\Users\Administrator\Desktop\人教6下TXT"
- 22 for dirpath, dirnames, filenames in os.walk(path):

- 29 lines[i] = re.sub(r'\[.*\]','',lines[i])
- 30 print(lines[i])
- 31 open(filename,'w').writelines(lines)
