Question

我正在尝试创建一个可浏览目录的脚本，如果该脚本被称为垃圾桶且早于3个月，则可以将其删除。

到目前为止，我已经有了这段代码。

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）时，它给我这个结果

/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，我得到了错误

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'

我正在尝试删除称为垃圾箱的文件夹，因为它的时间超过30秒（出于测试目的，实际上希望是3个月），我怎么会收到没有此类文件或目录错误的信息？

使用os.path.join(root, _dir)

例如：

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)

除非终端位于该目录中，否则您不能使用absolute path。

改为执行此操作：

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。

Python：FileNotFoundError：[Errno 2]没有这样的文件或目录：当目录存在时
