函数
alias
的目的是为别名本身创建一个昵称,并与该别名一起保存在内存中。我收到TypeError时无法正常工作。一个人如何减轻错误并使别名得到保存并与全名配对?执行
输入:
电话簿添加Bromley.Jones 12345
输出:
姓名:布罗姆利·琼斯
数12345
保存在电话簿中!
输入:
电话簿别名Bromley.Jones BJ
输出:
此功能不起作用。
Allonym具有与name相同的语言定义。
全名与名称具有相同的语言定义。
最佳答案
有两个问题。首先,在encounter
中:它将始终返回0
,除非您要搜索的项是第一个项,因为if
块位于for
内。找到后,您可以简单地将其返回:
def encounter(self, allonym):
for digit, allonyms in self.phoneDic.items():
if allonym in allonyms:
return digit
return 0
但是,这里的一个问题与第二个问题有关:字典中的键是字符串,但是您将其视为整数。我将更改上面的函数以在找不到时返回
None
。然后在alias
函数中:def encounter(self, allonym):
for digit, allonyms in self.phoneDic.items():
if allonym in allonyms:
return digit
return None
def alias(self, allonym, newallonym):
if newallonym:
phno = self.encounter(allonym)
if phno:
self.phoneDic[phno].append(newallonym)
print("Alias stated")
