在python中浏览文件路径

Browse for file path in python

我正在尝试创建一个带有浏览窗口的GUI,以查找特定文件。
我之前发现了这个问题:在Python

中浏览文件或目录对话框

尽管当我查找这些术语时,似乎并不是我想要的。

我需要的是可以从Tkinter按钮启动的东西,该按钮可以从浏览器返回所选文件的路径。

有人为此有资源吗?

编辑:好的,这样的问题已经回答了。对于任何有类似问题的人,请您进行研究,这里的代码确实起作用。不要在cygwin中对其进行测试。由于某种原因,它在那里不起作用。


我认为TkFileDialog对您可能有用。

import Tkinter
import tkFileDialog
import os

root = Tkinter.Tk()
root.withdraw() #use to hide tkinter window

currdir = os.getcwd()
tempdir = tkFileDialog.askdirectory(parent=root, initialdir=currdir, title='Please select a directory')
if len(tempdir) > 0:
    print"You chose %s" % tempdir

编辑:此链接有更多示例


这将生成仅带有一个名为"浏览"按钮的GUI,该GUI会打印出您从浏览器中选择的文件路径。可以通过更改代码段<*。type>来指定文件的类型。

from Tkinter import *
import tkFileDialog

import sys
if sys.version_info[0] < 3:
   import Tkinter as Tk
else:
   import tkinter as Tk


def browse_file():

fname = tkFileDialog.askopenfilename(filetypes = (("Template files","*.type"), ("All files","*")))
print fname

root = Tk.Tk()
root.wm_title("Browser")
broButton = Tk.Button(master = root, text = 'Browse', width = 6, command=browse_file)
broButton.pack(side=Tk.LEFT, padx = 2, pady=2)

Tk.mainloop()


我重新制作了Roberto的代码,但是用Python3进行了重写(只是微小的更改)。

您可以照原样复制并粘贴一个简单的演示.py文件,也可以仅复制函数" search_for_file_path"(以及相关的导入),然后将其作为函数放入程序中。

def search_for_file_path ():
    currdir = os.getcwd()
    tempdir = filedialog.askdirectory(parent=root, initialdir=currdir, title='Please select a directory')
    if len(tempdir) > 0:
        print ("You chose: %s" % tempdir)
    return tempdir


file_path_variable = search_for_file_path()
print ("\
file_path_variable ="
, file_path_variable)

在python 3中,它已重命名为filedialog。您可以通过askdirectory方法(事件)访问文件夹传递,如下所示。如果要选择文件路径,请使用askopenfilename

import tkinter
from tkinter import messagebox
from tkinter import filedialog

main_win = tkinter.Tk()
main_win.geometry("1000x500")
main_win.sourceFolder = ''
main_win.sourceFile = ''
def chooseDir():
    main_win.sourceFolder =  filedialog.askdirectory(parent=main_win, initialdir="/", title='Please select a directory')

b_chooseDir = tkinter.Button(main_win, text ="Chose Folder", width = 20, height = 3, command = chooseDir)
b_chooseDir.place(x = 50,y = 50)
b_chooseDir.width = 100


def chooseFile():
    main_win.sourceFile = filedialog.askopenfilename(parent=main_win, initialdir="/", title='Please select a directory')

b_chooseFile = tkinter.Button(main_win, text ="Chose File", width = 20, height = 3, command = chooseFile)
b_chooseFile.place(x = 250,y = 50)
b_chooseFile.width = 100

main_win.mainloop()
print(main_win.sourceFolder)
print(main_win.sourceFile )

注意:即使关闭main_win,变量的值仍然存在。但是,您需要将变量用作main_win的属性,即

main_win.sourceFolder

以先前的答案和在该线程中找到的答案为基础:如何在这里使Tkinter文件对话框成为焦点,是一种快速的方法,可以在Python 3中拉起文件选择器而无需查看修补窗口,也可以将浏览窗口拉至屏幕正面
