Question

我正在尝试将目录从一个位置复制到其他位置，并且我已经为此编写了代码。在执行IDE时给了我一个例外。

import sys
import os
from Tkinter import *
from tkCommonDialog import Dialog
import shutil
import tkFileDialog
import win32com.client

win = Tk()
win.title("Copying the Dorectory to specified location")
win.geometry("600x600+200+50")
win.resizable()
class Copy:

    def __init__(self,Obj):

        la = Label(win, text = "Source Directory is",font = "verdana 12 italic bold", width = 20,fg = "Red", bg = "WHITE", )
        la.grid(row=1, column =1)
        abc = "tk_chooseDirectory"
        bu = Button(text="Source", font = "Verdana 12 italic", command= abc )
        bu.grid(row =1 , column =3)


        la1 = Label(win, text = "DestibationDirectory is",font = "verdana 12 italic bold", width = 20,fg = "Red", bg = "WHITE", )
        la1.grid(row=2, column =1)
        abc1 = "tk_chooseDirectory"
        bu1 = Button(text="Destination", font = "Verdana 12 italic", command=abc1)
        bu1.grid(row =2 , column =3)


        def start():
            shutil.copy(abc, abc1)
        bu2 = Button(text="Copy", font= "Verdana 12 bold", command =start)
        bu2.grid(row =3, column =2)

obj = Copy(win)
win.mainloop()

这是我的代码，我面临的例外是

Exception in Tkinter callback
Traceback (most recent call last):
  File "C:\Python27\lib\lib-tk\Tkinter.py", line 1410, in __call__
    return self.func(*args)
  File "C:\Documents and Settings\Bharath Gupta\Desktop\task.py", line 38, in start
    shutil.copy(abc, abc1)
  File "C:\Python27\lib\shutil.py", line 116, in copy
    copyfile(src, dst)
  File "C:\Python27\lib\shutil.py", line 68, in copyfile
    raise Error("`%s` and `%s` are the same file" % (src, dst))
Error: `tk_chooseDirectory` and `tk_chooseDirectory` are the same file

请有人帮助我摆脱异常。

查看您的代码，并添加一些评论。

class Copy:
    def __init__(self,Obj):
        la = Label(win, text = "Source Directory is",font = "verdana 12 italic bold", width = 20,fg = "Red", bg = "WHITE", )
        la.grid(row=1, column =1)
        #SET abc HERE
        abc = "tk_chooseDirectory"
        bu = Button(text="Source", font = "Verdana 12 italic", command= abc )
        bu.grid(row =1 , column =3)


        la1 = Label(win, text = "DestibationDirectory is",font = "verdana 12 italic bold", width = 20,fg = "Red", bg = "WHITE", )
        la1.grid(row=2, column =1)
        #SET abc1 HERE
        abc1 = "tk_chooseDirectory"
        bu1 = Button(text="Destination", font = "Verdana 12 italic", command=abc1)
        bu1.grid(row =2 , column =3)


        def start():
            #RUN WITH abc AND abc1
            shutil.copy(abc, abc1)

但是你永远不会改变那些变量的值。因为你把它们初始化为同样的东西。您的复制命令正在尝试将某些内容复制到自身。（这就是错误所说的：

错误：tk_chooseDirectory和tk_chooseDirectory是同一个文件

您需要一种方法来输入您想要使用的两个目录，以便shutil.copy()能够达到您想要的效果。

请有人帮助我摆脱异常。

摆脱异常的一种可靠方法是这种模式：

try:
    #shutil naughtiness
except:
    pass

......但是那个肯定会引起同事的愤怒。

看起来在您的特定情况下，源和目标是完全相同的。在这种情况下，最合适的做法似乎是处理异常。特别是因为这只是复制的许多失败模式中的一种。您应该将每个用户升级为用户，因为用户应该知道如何解决它。

您处于令人羡慕的位置，您的代码可能已经准备好处理异常。试试

try:
    shutil.copy(abc, abc1)
except Error, e:
    tkMessageBox.showwarning(
        "Copying file",
        "Error while copying\n(%s)" % e.msg
    )

            except :
                tkMessageBox.showwarning("Copying file", "Error while copying\n(%s)")

        bn = Button(text="Copy", font="Verdana 12 italic", bg="Purple", fg="white", command=start)
        bn.pack(fill=X, expand=YES)
        bn.place(relx=0.50, rely=0.25, anchor=CENTER)

obj = Copy()
#obj.source(win)
#obj.destination(win)
win.mainloop()
