Question

我有一个老式的Python CGI脚本，旨在允许任意数量的已保存问题，并允许每个问题任意数量的已保存答案。我一直在尝试通过使它在列表上的索引为1来保存测试题的第二个答案，但是（预期的）作业似乎没有任何作用。

用于解析CGI值（未保存的值为saved_0_2）的函数是

def save_values():
    sys.stderr.write('save_values()\n')
    if get_cgi('submitted'):
        sys.stderr.write('submitted')
        sys.stderr.write(repr(cgi_form.keys()) + '\n')
        for key in cgi_form.keys():
            try:
                parts = key.split('_')
                entry = int(parts[1])
                slot = int(parts[2])
                if slot == 0:
                    saved['entries'][entry][1] = get_cgi(key)
                else:
                    sys.stderr.write('Entry: ' + str(entry))
                    sys.stderr.write('Slot: ' + str(slot))
                    sys.stderr.write(get_cgi(key))
                    sys.stderr.write(repr(saved['entries'][entry][2]))
                    saved['entries'][entry][2][slot - 1] = get_cgi(key)
                    sys.stderr.write(repr(saved['entries'][entry][2]))
            except IndexError:
                pass
        saved['index'] += 1
        sys.stderr.write(repr(saved) + '\n')
        cPickle.dump(saved, open(STORAGE + '.' + str(os.getpid()), 'w'))
        os.rename(STORAGE + '.' + str(os.getpid()), STORAGE)
    if get_cgi('entry'):
        open(ACCESS, 'a').write('Statement: ' +
          saved['entries'][int(get_cgi('entry'))][1] + '\n' + 'Response: ' +
          get_cgi('response') + '\n\n')

Apache日志中以saved_0_2填充“ It is。”的输出为：

但是下一次页面加载时没有带有现有答案的数组的索引1元素。此外，在保存程序中，我受到政府经济学家计算机病毒的打击。一切都说出我想要的值，以便将第二个（索引1）元素添加到列表中，但是赋值似乎并没有改变列表，这是在酸洗和保存之前。

感谢您的帮助...

我如何无法将项目添加到列表？
