Python 3でデータを保存してロードする

Question

データを保存して読み込むチーム名簿を作成する必要があります。私は他のすべてのものが機能するが、保存して読み込むという点まで持っている。

memberList = [] 
#get first menu selection from user and store in control value variable 
def __init__(self, name, phone, number): 
    self.__name = name 
    self.__phone = phone 
    self.__number = number 
def setName(self, name): 
    self.__name = name 
def setPhone(self, phone): 
    self.__phone = phone 
def setnumber(self, number): 
    self.__number = number 
def getName(self): 
    return self.__name 
def getPhone(self): 
    return self.__phone 
def getNumber(self): 
    return self.__number 
def displayData(self): 
    print("") 
    print("Player's Information") 
    print("-------------------") 
    print("Player's Name:", getName) 
    print("Player's Telephone number:", getPhone) 
    print("Player's Jersey number:", getNumber) 
def displayMenu(): 
    print("==========Main Menu==========") 
    print("1. Display Team Roster") 
    print("2. Add Member") 
    print("3. Remove Member") 
    print("4. Edit Member") 
    print("9. Exit Program") 
    print() 
    return int(input("Selection>")) 
menuSelection = displayMenu() 
def printMembers(memberList): 
    print("Current members: ") 
    if len(memberList) == 0: 
     print("No current members in memory.") 
    else: 
     x = 1 
     while x < len(memberList): 
      print(memberList[x],) 
      x = x + 1 
def addPlayer(memberList): # players as an argument 
    newName = input("Add a player's Name: ") 
    newPhone = input("Telephone number: ") 
    newNumber = input("Jersey number: ") 
    memberList.append(newName) 
    return memberList 
def removePlayer(memberList): 
    removeName = input("What name would you like to remove? ",) 
    # Don't redefine it! 
    if removeName in memberList: 
     del memberList[removeName] 
    else: 
     print("Sorry", removeName, "was not found!") 
    return memberList 
def editPlayer(memberList): 
    oldName = input("What name would you like to change? ",) 
    if oldName in memberList: 
     newName = input("What is the new name? ") 
     print("***", oldName, "has been changed to", newName) 
    else: 
     print("***Sorry", oldName, "was not found!") 
    return memberList 
def saveData(memberList): 
    filename=input("Filename to save: ",) 
    print("saving data...") 
    outfile=open(filename, "wt") 
    filename= '/Users\nativ\ Documents' 
    for x in memberList: 
     name = memberList[x].getName() 
     phone = memberList[x].getPhone() 
     number = memberList[x].getNumber() 
     outfile.write("name","age", 'number') 
    print("Data Saved") 
    outfile.close() 
def loadData(): 
    filename = input("Filename to load: ") 
    inFile = open(filename, "rt") 
def exitProgram(memberList): 
    print("Exiting Program...") 
while menuSelection != 9: 
    if menuSelection == 1: 
     printMembers = printMembers(memberList) 
     menuSelection = displayMenu() 
    elif menuSelection == 2: 
     memberList = addPlayer(memberList) 
     menuSelection = displayMenu() 
    elif menuSelection == 3: 
     memberList = removePlayer(memberList) 
     menuSelection = displayMenu() 
    elif menuSelection == 4: 
     memberList = editPlayer(memberList) 
     menuSelection = displayMenu() 
    elif menuSelection == 5: 
     memberList = saveData(memberList) 
     menuSelection = displayMenu() 
    elif menuSelection == 6: 
     memberList = loadData() 
    menuSelection = displayMenu() 
print('Welcome to the Team Manager') 
displayMenu() 

これは私が

Traceback (most recent call last): 
    File "C:/Users/nativ/PycharmProjects/Week2/Week 5.py", line 98, in <module> 
    memberList = saveData(memberList) 
    File "C:/Users/nativ/PycharmProjects/Week2/Week 5.py", line 73, in saveData 
    name = memberList[x].getName() 
TypeError: list indices must be integers or slices, not str

を取得していますエラーコードではname = memberList[int(x)].getName()をお試しください。ファイルからデータを読み込むときには文字列を読み込み、それをリストに入れるには整数にする必要があります。
