Question

我试过一遍又一遍地运行这段代码，但无法弄清楚问题。添加名称时，结果可以正常显示。当我编辑名称然后尝试显示名单时，我收到错误。错误是：

Traceback (most recent call last):
  File "Z:/Grantham University/programming essentials/Week 5 Cody Pillsbury.py", 
line 88, in <module>

DisplayTeamRoster(teamRoster)
  File "Z:/Grantham University/programming essentials/Week 5 Cody Pillsbury.py", 
line 39, in DisplayTeamRoster
   teamRoster[x].displayTeamRoster()
AttributeError: 'tuple' object has no attribute 'displayTeamRoster'

以下是代码：

import sys;

class Roster:
    name = ""
    phoneNumber = ""
    jersyNumber = 0
    def __init__(self, name, phoneNumber, jersyNumber):

Answer 1

editRoster()

中的这行代码

teamRoster[oldName] = (playerName, playerPhoneNumber, playerJersyNumber)

正在用Roster()替换teamRoster对象3-tuple。当您在该元组上调用displayRoster时，这会产生问题。

您需要修改Roster()对象到位：

teamRoster[oldName].playerName = playerName
teamRoster[oldName].platerPhoneNumber = playerPhoneNumber
teamRoster[oldName].platerJersyNumber = playerJersyNumber

然后你保持相同的对象，一切都能正常使用更新的值。

Answer 2

我的问题是editPerson方法中的拼写错误。我不得不改变：

def editPlayer(teamRoster):
    oldName = input("Please enter the player\'s name you would like to change:")
    if oldName in teamRoster:
        playerName = input("What is the player\'s new name:")
        playerPhoneNumber = input("What is the player\'s new phone number:")
        playerJersyNumber = input("What is the player\'s new jersey number:")
        teamRoster[oldName] = (playerName, playerPhoneNumber, playerJersyNumber)
    else:
        print(oldName, "was not found in the team roster!")
    return teamRoster

到

def editPlayer(teamRoster):
    oldName = input("Please enter the player\'s name you would like to change:")
    if oldName in teamRoster:
        playerName = input("What is the player\'s new name:")
        playerPhoneNumber = input("What is the player\'s new phone number:")
        playerJersyNumber = input("What is the player\'s new jersey number:")
        teamRoster[oldName] = Roster(playerName, playerPhoneNumber, playerJersyNumber)
    else:
        print(oldName, "was not found in the team roster!")
    return teamRoster

我需要做的就是放入名册，这样玩家就可以插入到Team Roster词典中。
