python - 初学者打开资源管理器以显示文件夹内容

问题描述

几天来，我一直在 Windows 7 上修改 Python 3.66。取得了良好的进展，但我完全坚持如何打开 Windows 资源管理器并显示我想要的文件夹内容。

我已经尝试了至少 7 种来自相关问题的不同解决方案，但似乎都没有。他们都可以很好地打开资源管理器，但从不使用我的 Folder_selected 变量。

explorer 位是最后一行代码。这是（我怀疑编码错误）来源：

#FRenum-v.04
#renumbers a folder of files to 01 onward preserving file extenders.
#Steve Shambles june 2018, my 2nd ever python program

from tkinter import filedialog
from tkinter import *
import os
import os.path
import subprocess

#user selects directory
root = Tk()
root.withdraw()                             #stop tk window opening
folder_selected = filedialog.askdirectory() #open file requestor

#change dir to folder selected by user,
os.chdir (folder_selected)
#path is now the dir
path=(folder_selected)

# read user selected dir   
files = os.listdir(folder_selected)

# inc is counter to keep track of what file we are working on
inc = 1 

for file in files:
    #store file extender in string file_ext
    file_ext = os.path.splitext(file)[1]

    # build new filename, starting with a "0" then 
    #value of inc then add file extender
    created_file=("0"+str(inc)+ file_ext)

    #if file does not exist rename it
    if not os.path.exists(created_file):
        os.rename(file,created_file)

        #next one please, until done
        inc = inc+1 #add to counter

#open explorer showing folder of renamed files   
subprocess.Popen(["C:\\Windows\\explorer.exe"]) 

#these do not work properly, opens in c: or my docs    
#subprocess.Popen(["C:\\Windows\\explorer.exe"+ folder_selected]) 
#subprocess.Popen(["C:\\Windows\\explorer.exe", folder_selected])    
#subprocess.Popen(["C:\\Windows\\explorer.exe","folder_selected"])

解决方案

这个问题是由 python/linux 和 windows 表示路径的差异引起的。我打印folder_selected并得到：

C:/Users/name/Documents/Zevel

您需要在调用后立即添加以下内容askdirectory()：

folder_selected = folder_selected.replace('/', '\\')

使路径对 Windows 可读，现在它看起来像：

C:\Users\name\Documents\Zevel

当然，你需要打电话subprocess.Popen(["explorer", folder_selected]) ，一切都会奏效。
