我不知道出了什么问题,但我不断得到这个
Tkinter 回调 Traceback 中的异常(最近一次调用最后一次):文件“/Library/Frameworks/Python.framework/Versions/7.3/lib/python2.7/lib-tk/Tkinter.py”,第 1410 行,调用 返回 self。 func(*args) 文件“/Users/Zane/Desktop/Factorial GUI.py”,第 72 行,在reveal2 self.text2.insert(0.0, message) 文件“/Library/Frameworks/Python.framework/Versions/7.3/ lib/python2.7/lib-tk/Tkinter.py",第 2986 行,插入 self.tk.call((self._w, 'insert', index, chars) + args) TclError: wrong # args: 应该是“.22186144.22187184 插入索引字符?tagList chars tagList ...?”
