python如何修改文件时间属性

1、获取文件的创建、修改、访问时间

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

def get_file_time(filename):
 filename = os.path.abspath(filename)
 create_time = os.path.getctime(filename) # 创建时间
 print('old create time:{}'.format(time.strftime("％Y-％m-％d ％H:％M:％S", time.localtime(create_time))))
 update_time = os.path.getmtime(filename) # 修改时间
 print('old update time:{}'.format(time.strftime("％Y-％m-％d ％H:％M:％S", time.localtime(update_time))))
 access_time = os.path.getatime(filename) # 访问时间
 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、访问时间（创建时间没查到怎么修改，暂时不记录）

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

def set_file_time(filename, updatetime, access_time):
 # 先传修改时间，再传访问时间
 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、放在同一个py方便直接复制使用

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

def get_file_time(filename):
 filename = os.path.abspath(filename)
 # 创建时间
 create_time = time.strftime("％Y-％m-％d ％H:％M:％S", time.localtime(os.path.getctime(filename)))
 # 修改时间
 update_time = time.strftime("％Y-％m-％d ％H:％M:％S", time.localtime(os.path.getmtime(filename)))
 # 访问时间
 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):
 # 先传修改时间，再传访问时间
 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、补充修改文件的创建时间

import os
import time

from pywintypes import Time # 可以忽视这个 Time 报错（运行程序还是没问题的）
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" # 时间格式
   # 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" # 创建时间
 mTime = "2019-02-02 00:01:03" # 修改时间
 aTime = "2019-02-02 00:01:04" # 访问时间
 fName = r"a.txt" # 可以是文件也可以是文件夹
 print(os.path.isdir(fName))
 modify_file_create_time(fName, cTime, mTime, aTime)
