window.title('文件上传')
window.geometry('550x200')
frm = tk.Frame(window)
frm.grid(padx='20', pady='30')
btn1 = tk.Button(frm, text='上传文件', font=('Arial', 12), width=10, height=1, command=upload_file)
btn1.grid(row=0, column=0, ipadx='3', ipady='3', padx='10', pady='20')
entry = tk.Entry(frm, width=40)
entry.grid(row=0, column=1)
def upload_file():
#指定上传mp4视频文件
# askopenfilename 1次上传1个；askopenfilenames1次上传多个
selectFile = tk.filedialog.askopenfilename(filetypes=(("MP4视频", "*.mp4"),))
