Python，檢查文件的保存時間

Question

目標是在每次修改（保存）列表中的文件時執行一些操作。

我不知道要繼續。最終的目標應該是這樣的：

files = ['file1.txt', 'file2.txt', 'file3,txt'] 

if (one of the files in files is modified): 
    Print '%s has been modified' % (filename) 

Answer 1

這將使用字典查一下時間和打印任何修改過的文件：

import os.path, time 
files = ['file1.txt', 'file2.txt', 'file3,txt'] 
changes = {"file1.txt":os.path.getmtime("file1.txt"),"file2.txt":os.path.getmtime("file2.txt"),"file3.txt":os.path.getmtime("file3.txt")} 
while True: 
    for f in files: 
     if changes.get(f) < os.path.getmtime(f): 
      print "File {} has been modified".format(f) 
      changes[f] = os.path.getmtime(f) 
     else: 
      print "No changes, going to sleep." 
    time.sleep(10)
