Python实现批量文件分类保存的示例代码

import datetime
import pprint
import shutil
import re

origin_dir = '原始文件/'
target_dir = '目标文件/'
files = os.listdir(origin_dir)

month_compile = re.compile('(20\d\d)([01][0-9])')
print(files)
file_dict = {}
for file in files:
    if file.endswith('.docx'):
        Word_file = os.path.join(origin_dir, file)
        month = month_compile.search(word_file)
        if month:
            month = month.groups()
            # print(month.groups())
            if month[-1] == '00':
                month = re.search('(20\d\d)0([01][0-9])', word_file).groups()
            t1 = '-'.join(month)
            if t1 in file_dict.keys():

            else:
                file_dict[t1] = [word_file]

pprint.pprint(file_dict)

if not os.path.exists(target_dir):
    os.mkdir(target_dir)
