单击tkinter上的按钮后如何播放视频

Question

I'm trying to make a video play after a button is clicked, but its not working. The error I get is SyntaxError (unicode error) 'unicodeescape' codec can't decode bytes in positiion 2-3: truncated\\UXXXXXXXX escape

rb1 = tk.Button(self, text = "Play", command=self.video).pack()

def video(self):
    import os

    os.system("C:\Users\Tim\Documents\Bicep.mp4")

Your quoting of the file path is causing this error. In python strings a backslash is used as an escape character to provide a means to enter special characters like newlines and unicode characters (eg: \© for the copyright character) . So the "\\Us" sequence is translated into an attempt to read a unicode character definition that is invalid as 's' is not a hexadecimal digit. You should either escape the backslashes ("c:\\Users\\Tim\\...") or use the raw string marker to indicate this string should not have escape code translations performed (ie: r"C:\\Users\\Tim..." ).
