我正在尝试创建一个查看目录的脚本，如果它被称为垃圾并且超过 3 个月，它可以被删除。

到目前为止，我有这个代码。

import os, sys, time
from subprocess import call
import path 



now = time.time()
cutoff = now - (30)#(91 * 86400)

path = '/users/shoot_station_5/documents/folderfordeletetest/'

for root, d_names, f_names in os.walk(path):
    print (root, d_names, f_names)
    for _dir in d_names:
        if time.ctime(os.path.getmtime(_dir)) < cutoff:
            print (_dir)

当我打印 (root, d_names, f_names) 它给了我这个结果

/users/shoot_station_5/documents/folderfordeletetest/ ['dont_delete', 'dont_delete_me'] ['.DS_Store']
/users/shoot_station_5/documents/folderfordeletetest/dont_delete ['trash'] ['.DS_Store']
/users/shoot_station_5/documents/folderfordeletetest/dont_delete/trash [] []
/users/shoot_station_5/documents/folderfordeletetest/dont_delete_me ['trash'] ['.DS_Store']
/users/shoot_station_5/documents/folderfordeletetest/dont_delete_me/trash [] []

运行最后一部分时，我收到错误

Traceback (most recent call last):
  File "/Users/shoot_station_5/Documents/scripts/walkdelete.py", line 16, in <module>
    if time.ctime(os.path.getmtime(_dir)) < cutoff:
  File "/anaconda3/lib/python3.6/genericpath.py", line 55, in getmtime
    return os.stat(filename).st_mtime
FileNotFoundError: [Errno 2] No such file or directory: 'dont_delete'

我试图将名为垃圾的文件夹删除，因为它的时间超过 30 秒（出于测试目的，实际上希望它是 3 个月）我怎么会得到没有这样的文件或目录错误？

absolute path除非您的终端位于该目录中，否则您无法使用。

改为这样做：

os.chdir(r"C:\Users\rajat.prakash\Downloads")
fresh = max(latest_file, key = os.path.getctime)
print(fresh)

它将打印最新下载的 Excel 报告，但首先更改目录。

利用os.path.join(root, _dir)

前任：

import os, sys, time
from subprocess import call
import path 

now = time.time()
cutoff = now - (30)#(91 * 86400)

path = '/users/shoot_station_5/documents/folderfordeletetest/'

for root, d_names, f_names in os.walk(path):
    print (root, d_names, f_names)
    for _dir in d_names:
        if time.ctime(os.path.getmtime(os.path.join(root, _dir))) < cutoff:
            print (_dir)
