[Python知识库]python获取文件大小、最后修改日期、创建日期、最后访问日期 计算时间差

import os, datetime

filename = '/Users/kwsy/kwsy/coolpython/demo.py'
# 文件大小
filesize = os.path.getsize(filename)
print(filesize)     # 字节数

# 文件创建日期
create_time = os.path.getctime(filename)        # 返回的是时间戳
print(datetime.datetime.fromtimestamp(create_time))

# 文件最近访问时间
access_time = os.path.getatime(filename)
print(access_time)

# 文件最近修改时间
modify_time = os.path.getmtime(filename)
print(modify_time)

计算时间差

def del_over_2days():
    raw_dir = r"D:\download\flink"
    file_list = os.listdir(raw_dir)
    for file in file_list:
        file_path = os.path.join(raw_dir, file)
        print(file_path)
        modify_time = os.path.getmtime(file_path)
        print(modify_time)
        print(datetime.fromtimestamp(modify_time))
        days = (datetime.now() - datetime.fromtimestamp(modify_time) ).days
        print(days)
    print(len(file_list))
