本文主要是介绍(Python文件处理)doc文档转UTF-8格式的TXT文档,对大家解决编程问题具有一定的参考价值,需要的程序猿们随着小编来一起学习吧!
目录
- doc转txt
- UTF-8去BOM
- 参考:
目录下所有doc文档转txt,本来想直接用SaveAs规定转存编码格式,但是得到的是带BOM的UTF-8格式,所以又加了个去BOM的过程。
doc转txt
得到带BOM的UTF-8:
import os import sys import codecs import fnmatch import win32com.client PATH = os.path.abspath(os.path.dirname(sys.argv[0])) doc_path = PATH + '/data/doc/' txt_path = PATH + '/data/txt/' def convert_dir_to_txt(): """ 将默认整个文件夹下的文件都进行转换 :return: """ for root, dirs, files in os.walk(doc_path): for _dir in dirs: pass for _file in files: if fnmatch.fnmatch(_file, '*.doc'): store_file = txt_path + _file[:-3] + 'txt' elif fnmatch.fnmatch(_file, '*.docx'): store_file = txt_path + _file[:-4] + 'txt' word_file = os.path.join(root, _file) dealer.Documents.Open(word_file) try: dealer.ActiveDocument.SaveAs(store_file, FileFormat=7, Encoding=65001) except Exception as e: print(e) dealer.ActiveDocument.Close() dealer = win32com.client.gencache.EnsureDispatch('Word.Application') convert_dir_to_txt()
UTF-8去BOM
限制一次阅读量(因为BOM只在最开头,所以不需要遍历整个文件):
BUFSIZE = 4096 BOMLEN = len(codecs.BOM_UTF8)
在convert_dir_to_txt函数的末尾增加去BOM的代码段:
for root, dirs, files in os.walk(txt_path): for _dir in dirs: pass for _file in files: path = txt_path+_file try: with open(path, "r+b") as fp: chunk = fp.read(BUFSIZE) if chunk.startswith(codecs.BOM_UTF8): i = 0 chunk = chunk[BOMLEN:] while chunk: fp.seek(i) fp.write(chunk) i += len(chunk) fp.seek(BOMLEN, os.SEEK_CUR) chunk = fp.read(BUFSIZE) fp.seek(-BOMLEN, os.SEEK_CUR) fp.truncate() except Exception as e: print(e)
完事儿。
