python如何修改文件时间属性_Python

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)
