Ask multiple directories dialog in Tkinter

Having had the same problem I developed my own solution. With this you can select one directory at a time then select cancel when you are finished.

The function the returns a list of the directories you have selected.

def fun_directory_selector(request_string: str, selected_directory_list: list, search_directory):    directory_path_string = filedialog.askdirectory(initialdir=search_directory, title=request_string)       if len(directory_path_string) > 0:        selected_directory_list.append(directory_path_string)        fun_directory_selector('Select the next Directory or Cancel to end',                                selected_directory_list,                               os.path.dirname(directory_path_string))    return selected_directory_list

The OP asked for a solution with Tkinter which isn't available but a solution is possible with wxPython-Phoenix
