Here is an example of storing the directory path as a global variable and using that to populate a Label.
这是将目录路径存储为全局变量并使用它来填充标签的示例。
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()
