python-3.x - 电话簿不能存储 2 个同姓的人

Question

电话簿不能存储多个同名的人。例如，如果我有一个姓氏 x 的条目，并且我尝试创建一个姓氏 x 的新条目，它将用最后一个 x 输入的信息替换之前的 x。这是code.blablablablablabla（我不能说更多，但它不允许我发布）

Answer 1

我觉得

new_entries[last_name] = {'Last Name':last_name, 'First Name':name, 'Age':age, 'Telephone':phone,'Personal Notes':{'1.':'', '2.':''}}

应该是一个包含字典而不仅仅是字典的列表。

new_entries[last_name] = [{'Last Name':last_name, 'First Name':name, 'Age':age, 'Telephone':phone,'Personal Notes':{'1.':'', '2.':''}}]

这样，您可以将另一个项目附加到存储在同一last_name键下的列表中。

然后，您必须更新其余代码以处理此新数据结构。
