Python 3.2 Tkinter-键入目录作为文件复制的源 [英] Python 3.2 Tkinter - typed in directory to be source for file copying

问题描述

我正在尝试制作一个简单的工具，该工具会将具有特定扩展名的文件从一个地方复制/移动到另一个地方.一切工作都很好，但是我正在尝试键入要复制的目录，然后选择要复制到的目录.

I am trying to make a simple tool which will copy/move files with certain extension from one place to another. Everything is working out pretty much fine, but I am trying to make it possible to type in the directory where you want to copy from, and choose the directory where you want to copy to.

myGUI=Tk()
myGUI.geometry("400x200+100+200")
myGUI.title('Copy dat')

Source=StringVar()
Destination=StringVar()

MySource=Entry(myGUI, textvariable=Source).grid(row=9, column=2)
MyDestination=Entry(myGUI, textvariable=Destination).grid(row=10, column=2)


def copyy():
    source = os.listdir("Source")
    destination = "Destination"
    for files in source:
        if files.endswith(".jpg"):
            shutil.copy(files, destination)

button1=Button(myGUI, text="  Copy  ", command=copyy).grid(row=3, column=0)

但是，如果我单击按钮，该错误消息将显示Windows无法找到名为/Source或类似名称的目录.所以我知道source = os.listdir("Source")是问题所在.而且我猜destination = "Destination"也不正确. 如果我将整个路径放在代码中，则复制按钮可以很好地工作，但是我希望工具的用户可以在窗口中写入路径.请帮忙.

But if I click on my button, the error message says that windows can't find directory named /Source or something like that. So I understand source = os.listdir("Source")is the problem. And I guess destination = "Destination" is also incorect. If I put the whole path in the code the copy button works well, but I want it to be possible to write the path in the window by the user of the tool. Please help.

整个代码(如果需要)

import shutil
import os
from tkinter import *


myGUI=Tk()
myGUI.geometry("400x200+100+200")
myGUI.title('Copy dat')


Source=StringVar()
Destination=StringVar()

MySource=Entry(myGUI, textvariable=Source).grid(row=9, column=2)
MyDestination=Entry(myGUI, textvariable=Destination).grid(row=10, column=2)

def copyy():
        source = os.listdir('Source')
        destination = "Destination"
        for files in source:
            if files.endswith(".jpg"):
                shutil.copy(files, destination)

def movee():
        source = os.listdir("C:/Users/PC/Desktop/python testing/")
        destination = "C:/Users/PC/Desktop/python testing/destination"
        for files in source:
            if files.endswith(".jpg"):
                shutil.move(files, destination)

label1=Label(myGUI, text='Welcome to the copy utility', fg='Blue').grid(row=0,column=2)
label2=Label(myGUI, text='Ultimate JPG mover', fg='Black').grid(row=1,column=0)
label3=Label(myGUI, text='(Thing\'s actually pretty useless)',   fg='Black').grid(row=2,column=0)

button1=Button(myGUI, text="  Copy  ", command=copyy).grid(row=3, column=0)
button2=Button(myGUI, text="  Move  ", command=movee).grid(row=5, column=0)

myGUI.mainloop()

推荐答案

我进行了一些修改:

• 使用了class(更好的编码技术)
• 使用了filedialog(用于获取路径)
• 创建了Browse按钮
• 修改了copyy&的代码movee.

• Used class (better coding technique)
• Used filedialog(for getting the path)
• Created Browse button
• Modified your code for copyy & movee.

这是:

import shutil
import os
from tkinter import *
import tkinter.filedialog as fdialog

class MainClass():

    def __init__(self,master):
        self.parent=master
        self.gui()

    def gui(self):
        self.Source=StringVar()
        self.Destination=StringVar()

        MySource=Entry(myGUI, textvariable=self.Source).grid(row=9, column=2)
        browse=Button(myGUI,text="Browse",command=lambda:self.Source.set(fdialog.askopenfilename(filetypes=[("JPEG File",'.jpg')]))).grid(row=9, column=3)
        MyDestination=Entry(myGUI, textvariable=self.Destination).grid(row=10, column=2)
        browse1=Button(myGUI,text="Browse",command=lambda:self.Destination.set(fdialog.askdirectory())).grid(row=10, column=3)

        label1=Label(myGUI, text='Welcome to the copy utility', fg='Blue').grid(row=0,column=2)
        label2=Label(myGUI, text='Ultimate JPG mover', fg='Black').grid(row=1,column=0)
        label3=Label(myGUI, text='(Thing\'s actually pretty useless)',   fg='Black').grid(row=2,column=0)

        button1=Button(myGUI, text="  Copy  ", command=self.copyy).grid(row=3, column=0)
        button2=Button(myGUI, text="  Move  ", command=self.movee).grid(row=5, column=0)


    def copyy(self):
        source_file=self.Source.get()
        if source_file.endswith(".jpg"):
            shutil.copy(source_file, self.Destination.get())

    def movee(self):
        source_file=self.Source.get()
        if source_file.endswith(".jpg"):
            shutil.move(source_file, self.Destination.get())

if __name__ == '__main__':
    myGUI=Tk()
    app=MainClass(myGUI)
    myGUI.geometry("400x200+100+200")
    myGUI.title('Copy dat')
    myGUI.mainloop()
