Python 獲取文件的創建、修改、訪問時間並更改修改、訪問時間

1、獲取文件的創建、修改、訪問時間

參考鏈接： 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)  # 創建時間
    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)  # 訪問時間
    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、訪問時間（創建時間沒查到怎么修改，暫時不記錄）

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

def set_file_time(filename, updatetime, access_time):
    # 先傳修改時間，再傳訪問時間
    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py方便直接復制使用

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


def get_file_time(filename):
    filename = os.path.abspath(filename)
    # 創建時間
    create_time = time.strftime("%Y-%m-%d %H:%M:%S", time.localtime(os.path.getctime(filename)))
    # 修改時間
    update_time = time.strftime("%Y-%m-%d %H:%M:%S", time.localtime(os.path.getmtime(filename)))
    # 訪問時間
    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):
    # 先傳修改時間，再傳訪問時間
    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、補充修改文件的創建時間
