python如何修改文件時(shí)間屬性

更新時(shí)間：2021年02月05日 12:01:07 作者：withChengChen

這篇文章主要介紹了python修改文件時(shí)間屬性的方法，幫助大家更好的理解和使用python，感興趣的朋友可以了解下

1、獲取文件的創(chuàng)建、修改、訪問(wèn)時(shí)間
2、更改文件的修改、訪問(wèn)時(shí)間（創(chuàng)建時(shí)間沒(méi)查到怎么修改，暫時(shí)不記錄）
3、放在同一個(gè)py方便直接復(fù)制使用
4、補(bǔ)充修改文件的創(chuàng)建時(shí)間

1、獲取文件的創(chuàng)建、修改、訪問(wèn)時(shí)間

# -*- encoding=utf-8 -*-
import os
import time


def get_file_time(filename):
  filename = os.path.abspath(filename)
  create_time = os.path.getctime(filename) # 創(chuàng)建時(shí)間
  print('old create time:{}'.format(time.strftime("%Y-%m-%d %H:%M:%S", time.localtime(create_time))))
  update_time = os.path.getmtime(filename) # 修改時(shí)間
  print('old update time:{}'.format(time.strftime("%Y-%m-%d %H:%M:%S", time.localtime(update_time))))
  access_time = os.path.getatime(filename) # 訪問(wèn)時(shí)間
  print('old access time:{}'.format(time.strftime("%Y-%m-%d %H:%M:%S", time.localtime(access_time))))
  return create_time, update_time, access_time


if __name__ == '__main__':
  get_file_time('E:/a.txt')

2、更改文件的修改、訪問(wèn)時(shí)間（創(chuàng)建時(shí)間沒(méi)查到怎么修改，暫時(shí)不記錄）

# -*- encoding=utf-8 -*-
import os
import time

def set_file_time(filename, updatetime, access_time):
  # 先傳修改時(shí)間，再傳訪問(wèn)時(shí)間
  filename = os.path.abspath(filename)
  new_updatetime = time.mktime(time.strptime(updatetime, '%Y-%m-%d %H:%M:%S'))
  new_access_time = time.mktime(time.strptime(access_time, '%Y-%m-%d %H:%M:%S'))
  os.utime(filename, (new_access_time, new_updatetime))


if __name__ == '__main__':
  set_file_time('E:/a.txt', '2018-01-08 10:50:20', '2019-07-15 04:03:01')

3、放在同一個(gè)py方便直接復(fù)制使用

# -*- encoding=utf-8 -*-
import os
import time


def get_file_time(filename):
  filename = os.path.abspath(filename)
  # 創(chuàng)建時(shí)間
  create_time = time.strftime("%Y-%m-%d %H:%M:%S", time.localtime(os.path.getctime(filename)))
  # 修改時(shí)間
  update_time = time.strftime("%Y-%m-%d %H:%M:%S", time.localtime(os.path.getmtime(filename)))
  # 訪問(wèn)時(shí)間
  access_time = time.strftime("%Y-%m-%d %H:%M:%S", time.localtime(os.path.getatime(filename)))
  return create_time, update_time, access_time


def set_file_time(filename, updatetime, access_time):
  # 先傳修改時(shí)間，再傳訪問(wèn)時(shí)間
  filename = os.path.abspath(filename)
  new_update_time = time.mktime(time.strptime(updatetime, '%Y-%m-%d %H:%M:%S'))
  new_access_time = time.mktime(time.strptime(access_time, '%Y-%m-%d %H:%M:%S'))
  os.utime(filename, (new_access_time, new_update_time))


def debug():
  create_time, update_time, access_time = get_file_time('E:/a.txt')
  set_file_time('E:/a.txt', update_time, access_time)
  get_file_time('E:/a.txt')


if __name__ == '__main__':

  debug()

4、補(bǔ)充修改文件的創(chuàng)建時(shí)間

import os
import time

from pywintypes import Time # 可以忽視這個(gè) Time 報(bào)錯(cuò)（運(yùn)行程序還是沒(méi)問(wèn)題的）
from win32con import FILE_FLAG_BACKUP_SEMANTICS
from win32con import FILE_SHARE_WRITE
from win32file import CloseHandle
from win32file import CreateFile
from win32file import GENERIC_WRITE
from win32file import OPEN_EXISTING
from win32file import SetFileTime


def modify_file_create_time(filename, create_time_str, update_time_str, access_time_str):
  try:
    format_str = "%Y-%m-%d %H:%M:%S" # 時(shí)間格式
    # f = CreateFile(filename, GENERIC_READ | GENERIC_WRITE, 0, None, OPEN_EXISTING, 0, 0)
    f = CreateFile(filename, GENERIC_WRITE, FILE_SHARE_WRITE, None, OPEN_EXISTING,
            FILE_FLAG_BACKUP_SEMANTICS, 0)
    create_time = Time(time.mktime(time.strptime(create_time_str, format_str)))
    update_time = Time(time.mktime(time.strptime(update_time_str, format_str)))
    access_time = Time(time.mktime(time.strptime(access_time_str, format_str)))
    SetFileTime(f, create_time, update_time, access_time)
    CloseHandle(f)
    print('update file time success:{}/{}/{}'.format(create_time_str, update_time_str,
                             access_time_str))
  except Exception as e:
    print('update file time fail:{}'.format(e))


if __name__ == '__main__':
  cTime = "2019-12-13 21:51:02" # 創(chuàng)建時(shí)間
  mTime = "2019-02-02 00:01:03" # 修改時(shí)間
  aTime = "2019-02-02 00:01:04" # 訪問(wèn)時(shí)間
  fName = r"a.txt" # 可以是文件也可以是文件夾
  print(os.path.isdir(fName))
  modify_file_create_time(fName, cTime, mTime, aTime)
