Question

嘿，谢谢你抽出时间帮助我，我会直截了当地说：这只是一个小项目，我已经开始在我的GCSE之前练习我的Python技能了当前的问题我正在将一个数字添加到列表中，因为我已经完成了程序的每个部分。我设法解决所有当前的问题，但是，我无法解决这个问题所有/任何有关此问题的反馈/使程序更有效率将不胜感激。谢谢。

##code##
name = input("hello user what is your name?")
print("thank you for using our program:",name.title(),)
userchoice = input("which program would you like to use: add numbers,minus 
numbers, alphabetical word order?")
#add numbers#
numList = []
addnewnumber = input ("would you like to add a new number?")
while addnewnumber == 'yes':
    newnumber = input("what is your number?")
    numList.append()
if addnewnumber == 'no':
    numListsum = sum(numList)
    print (numListsum)

TypeError: append() takes exactly one argument (0 given)

Answer 1

这对我有用->

append((item1 , item2))

Answer 2

错误消息的含义正是它所说的：.append()希望您传递一个参数，但实际上您没有传递任何参数。试试这个：

numList.append(newnumber)

Answer 3

正确的语法是这样的：

numList = []
addnewnumber = input ("would you like to add a new number?")
while addnewnumber == 'yes':
    newnumber = input("what is your number?")
    numList.append(newnumber)

问题是您需要将值传递给append的{{1}}方法，以便追加它。

Answer 4

您的numList.append()必须有一个参数因此，请更改为此numList.append(newnumber)。

Answer 5

实际上在append函数
修复while循环

更新代码以执行您想要的操作：

name = input("hello user what is your name?")
print("thank you for using our program:",name.title(),)
userchoice = input("which program would you like to use: add numbers,minus 
numbers, alphabetical word order?")
#add numbers#
numList = []
addnewnumber = input ("would you like to add a new number?")
while addnewnumber == 'yes':
    newnumber = input("what is your number?")
    numList.append(newnumber)
    addnewnumber = input ("would you like to add a new number?")
numListsum = sum(numList)
print (numListsum)

TypeError：append（）只接受一个参数（给定0）如何解决？
