这是我的计划：
class member:
name = ""
phone = ""
number = 0
def init(self, name, phone, number):
self.name = name
self.phone = phone
self.number = number

self.name = name

self.phone = phone

self.number = number

return self.name
def getPhone(self):
return self.phone
def getNumber(self):
return self.number
def displayData(self):
print("")
print("Name:", self.name)
print("Phone:", self.phone)
print("Jersey Number:", self.number)
def displayMenu():
print("")
print("==========Main Menu==========")
print("1. Display Team Roster.")
print("2. Add Member.")
print("3. Remove Member.")
print("4. Edit Member.")
print("5. Save Data.")
print("6. Load Data.")
print("9. Exit Program.")
print("")
return int(input("Selection> "))
def printMembers(memberList):
if len(memberList) == 0:
print("No Current Members in Memory.")
else:
for x in memberList.keys():
memberList[x].displayData()
def addMember(memberList):
newName = input("Enter new member's name: ")
newPhone = input("Contact phone number: ")
newNumber = int(input("Jersey number: "))
memberList[newName] = member(newName,newPhone,newNumber)
#An updated list is returned.
return memberList
def removeMember(memberList):
removeName = input("Enter member name to be Removed: ")
#First, check to see if the name given, already exists in the list.
if removeName in memberList:
#Use the del key to delete the entry at the given name.
del memberList[removeName]
else:
print("Member not found in list.")
#An updated list is returned.
return memberList
def editMember(memberList):
#get the name of the member to be edited.
oldName = input("Enter the name of the member yopu want to edit. ")
#See if name is already in the list, if yes, get the index of the.
#given name, accept the new one, and replace the name in the list.
#with the new name.
#An updated list is returned.
if oldName in memberList:
newName = input("Enter the member's new name: ")

outFile.write(name+","+phone+","+number+"\n")
print("Data saved.")
outFile.close()
def loadData():
memberList ={}
filename = input("Filename to Load: ")
inFile = open(filename, "rt")
print("Loading Data...")
while True:
#Read in a line of text from the text file.
inLine = inFile.readline()
#If the line is empty, stop loading data.
if not inLine:
break
inLine = inLine[:-1]
name, phone, number = inLine.split(",")
memberList[name] = member(name, phone, int(number))
print("Data Loaded Successfully")
inFile.close()
return memberList
print("Welcome to the Team Manager")
#Create an empty dictionary by changing tthe [] to {}
memberList = {}
#Get the first menu selection from the user and store it in a control value variable.
menuSelection = displayMenu()
#The main program loop will detect the correct entry from the user and call the appropriate.
#method from the user's selection.
while menuSelection != 9:

print ("Exiting Program...")
这是我的错误：

有什么建议吗？
答案 0 :(得分：3)
您将初始化方法命名为init;正确的名称是__init__。双重下划线是Python如何表示为Python“特殊”使用保留的名称。通过不使用正确的名称，调用了超类（object'）__init__，但它不带参数，因此您得到错误。
旁注：saveData中有另一个错误;最后print和close调用几乎肯定会缩减，因此您可以编写所有数据，而不只是单个项目。
另外：
while True:
#Read in a line of text from the text file.
inLine = inFile.readline()
#If the line is empty, stop loading data.
if not inLine:
break
inLine = inLine[:-1]
name, phone, number = inLine.split(",")
memberList[name] = member(name, phone, int(number))
（在文件顶部导入csv）：
for name, phone, number in csv.reader(inFile):
memberList[name] = member(name, phone, int(number))
为你处理换行符和分割逗号，并且不涉及反复调用.readline()的无限循环的反模式（即使这不是CSV，迭代的正确方法）行是for inLine in inFile:，这避免了while，readline和if not inLine: break; for inLine in map(str.rstrip, inFile):避免了明确切断尾随换行符的需要。）

你错过了__。您的
def init(self, name, phone, number):
self.name = name
self.phone = phone
self.number = number
必须是
def __init__(self, name, phone, number):
self.name = name
self.phone = phone
self.number = number
