Python 太空入侵者:高分关键错误
所以,我让我的程序正常工作,从上次开始,一切都很好,直到我不得不插入一个高分系统使用连接。我已经回答了之前提出的关于高分的一个问题: 由于该人询问的程序与我的想法非常吻合,我决定使用shelve模块保存score变量。在插入变量和模块并在Pycharm上重新格式化文件以查看是否一切正常之后。我得到这个错误(这是错误的前半部分): 现在,我认为上半场不是问题所在,就像我之前添加分数和搁置一样,它仍然显示了这一点,程序将按照我的意愿运行 因此,我认为这后半部分是主要问题:Python 太空入侵者:高分关键错误,python,python-3.x,pygame,pycharm,Python,Python 3.x,Pygame,Pycharm,所以,我让我的程序正常工作,从上次开始,一切都很好,直到我不得不插入一个高分系统使用连接。我已经回答了之前提出的关于高分的一个问题: 由于该人询问的程序与我的想法非常吻合,我决定使用shelve模块保存score变量。在插入变量和模块并在Pycharm上重新格式化文件以查看是否一切正常之后。我得到这个错误(这是错误的前半部分): 现在,我认为上半场不是问题所在,就像我之前添加分数和搁置一样,它仍然显示了这一点,程序将按照我的意愿运行 因此,我认为这后半部分是主要问题: Traceback (mo
