关于使用input（）.split（）和3+项

Question

我目前正在开发一个处理用户输入的程序，我遇到了一个情况，在一个input()下需要多个返回，一开始我不知道当我得到一个值错误时我在做什么，直到我查了怎么做，它向我展示了这一点，并且在使用input().split()的两个输入时运行良好

class userinput():
def __init__(self, name,lista,listb,listc,listd):
    self.name=""
    self.lista=lista
    self.listb=listb
    self.listc=listc
    self.listd=listd






def set_lists(self):
    print("Do you want to create lists")
    decision = input()       
    if decision == "yes":   
        print("how many lists would you like to create?(up to 4)")
        decision2= int(input())
        if decision2 == 1:
            print("what would you like the list to be named")
            self.lista=input()
            print("you have created 1 list, with the name:"+ self.lista)                                         

        elif decision2 == 2:
            print("what would you like your lists to be?")
            self.lista,self.listb=input().split(",")
            print("You have created 2 lists with the names," + self.lista ,self.listb)

        elif decision2 == 3:
            print("what name would you like your first 2 lists to be")
            self.lista,self.listb = input().split(",")
            print("finally, the name for your third")
            self.listc = input()
            print("you have created 3 lists with the names," +self.lista,self.listb,self.listc)
        elif decision2 == 4:
            print("what name would you like your first 2 lists to be")
            self.lista,self.listb = input().split(",")
            print("finally, for your last 2 lists") 
            self.listc,self.listd=input().split(",")
            print("you have created three lists with the names of," +self.lista,self.listb,self.listc,self.listd)
        else:
            print("quitting")
            return

    else:
        print("quitting")

我的问题：似乎没有必要对4个输入使用2input().split()，有没有必要清理？
