Python 获取文件的创建、修改、访问时间并更改修改、访问时间

1、获取文件的创建、修改、访问时间

参考链接： https://www.cnblogs.com/likeatree/p/4280388.html

# -*- 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

    modify_file_create_time(folder, cTime, mTime, aTime)
    modify_file_create_time(file, cTime, mTime, aTime)
