我是 python 的新手，我正在尝试创建一个用于桁架分析的简单 GUI 应用程序。问题是在我在文本小部件中输入数据并将其保存在 txt 文件中后，数据带有我无法删除的单引号.我尝试使用 .strip 但仍然无法正常工作。我得到以下输出；

nodes = {'1': ['0', '0'], '2': ['1', '1'], '3': ['2', '2'], '4': ['3', '3'], '5': ['4', '4'], '6': ['5', '5']}

虽然我期待这个输出；

nodes = {1: [0, 0], 2: [1, 1], 3: [2, 2], 4: [3, 3], 5: [4, 4'], 6: [5, 5]}

我的代码在下面，对代码的庞大感到抱歉...有人可以帮我解决这个问题吗？提前致谢。
