Python3， 多种方法实现文件/目录的监听，只想说一个字：泰裤辣。

import os
import time
# 监听的目录路径
path_to_watch = 'D:\project'
# 初始化目录中的文件列表
# before = dict([(f, None) for f in os.listdir(path_to_watch)])
before = [f for f in os.listdir(path_to_watch)]
print(before)
def do_something(added):
    print('Added:', ', '.join(added))
while True:
    time.sleep(1)
    # 获取目录中的文件列表
    after = [f for f in os.listdir(path_to_watch)]
    # 获取新增的文件列表
    added = [f for f in after if f not in before]
    if added:
        # 打印新增的文件名称
        do_something(added)
    # 更新目录中的文件列表
    before = after

实现功能：
  使用os的stat函数，实现文件/目录的监听
'''
import os
import time
def file_monitor(path):
    # 获取初始文件状态
    last_stat = os.stat(path)
    while True:
        # 获取当前文件状态
        current_stat = os.stat(path)
        # 检查文件状态是否发生变化
        if current_stat != last_stat:
            print("File has been modified!")
            # 更新文件状态
            last_stat = current_stat
        # 休眠一段时间后再次检测
        time.sleep(1)
# 监听文件
file_monitor("path/to/file.txt")
