python如何遍历指定路径下所有文件（按按照时间区间检索）

#conding=utf8 
import os 
import time
g = os.walk(r"F:\学习资料\week_home")
def judge_time_file(path, file, update_time):
  if not file.endswith(('.doc','.docx')):
    return False
  start_time = time.mktime(time.strptime('2020-04-12 00:00:00', "%Y-%m-%d %H:%M:%S"))
  end_time  = time.mktime(time.strptime('2020-05-23 00:00:00', "%Y-%m-%d %H:%M:%S"))
  # print(start_time , update_time , end_time)
  if start_time < update_time < end_time:
    return True
  return False

data_list = []

for path, dir_list, file_list in g:
  for file_name in file_list:
    local_time = os.stat(os.path.join(path, file_name)).st_mtime
    if judge_time_file(path, file_name, local_time):
      data_list.append([os.path.join(path, file_name), time.strftime("%Y-%m-%d %H:%M:%S",time.localtime(local_time))])
data_list.sort(key=lambda x:x[1])
print(*data_list, sep='\n')
