Python에서 파일을 다운로드할 때 \'권한 오류: [Errno 13] 권한 거부됨\'을 수정하는 방법은 무엇입니까?

import os

def download():
    # get selected line index
    index = films_list.curselection()[0]
    # get the line's text
    selected_text = films_list.get(index)
    directory = filedialog.askdirectory(parent=root, 
                                        title="Choose where to save your movie")
    place_to_save = directory + '/' + selected_text
    
    # Verify that the path points to a file
    if not os.path.isfile(place_to_save):
        raise PermissionError("Permission denied: {}".format(place_to_save))
    
    with open(place_to_save, 'wb') as file:
        connect.retrbinary('RETR ' + selected_text, file.write)
    tk.messagebox.showwarning('File downloaded', 
                              'Your movie has been successfully downloaded!' 
                              '\nAnd saved where you asked us to save it!!')
