python tkInter浏览文件夹按钮

Question

我想使用tkinter制作浏览文件夹按钮并将路径存储到变量中。到目前为止，我能够打印路径，但我无法将其存储在变量中。你能给些建议么？

下面我附上我使用的代码。

from tkinter import filedialog 
from tkinter import * 

def browse_button(): 
    filename = filedialog.askdirectory() 
    print(filename) 
    return filename 


root = Tk() 
v = StringVar() 
button2 = Button(text="Browse", command=browse_button).grid(row=0, column=3) 

mainloop() 

非常感谢您！

下面是将目录路径存储为全局变量并使用它填充标签的示例。

from tkinter import filedialog 
from tkinter import * 

def browse_button(): 
    # Allow user to select a directory and store it in global var 
    # called folder_path 
    global folder_path 
    filename = filedialog.askdirectory() 
    folder_path.set(filename) 
    print(filename) 


root = Tk() 
folder_path = StringVar() 
lbl1 = Label(master=root,textvariable=folder_path) 
lbl1.grid(row=0, column=1) 
button2 = Button(text="Browse", command=browse_button) 
button2.grid(row=0, column=3) 

mainloop()
