问题描述
print("You may invite up to six people to your party.")
name = input("Enter invitee's name (or just press enter to finish): ")
nameList = ["","","","","",""]
currentName = 0
while name != "":
if currentName > 5:
break #If more than 6 names are input, while loop ends.
else:
nameList[currentName] = name
name = input("Enter invitee's name (or just press enter to finish): ")
currentName = currentName + 1
for i in len(nameList):
invitee = nameList[i]
print(invitee + ", please attend our party this Saturday!")

您的代码唯一的语法问题是您无法for i in len(nameList)做for i in len(nameList)如果要循环一定次数，则必须使用range() 。
如果将最后一部分更改为：
for i in range(len(nameList)): # range(5) makes a list like [0, 1, 2, 3, 4]
invitee = nameList[i]
print(invitee + ", please attend our party this Saturday!")
2楼
len(nameList)返回一个整数，您应该改为调用range(len(nameList)) 。
但是，如果您这样编写代码，则代码将更加简洁：
print("You may invite up to six people to your party.")
name_list = []
for current_name in range(6):
name = input("Enter invitee's name (or just press enter to finish): ")
if not name:
break
name_list.append(name)
for invitee in name_list:
print(invitee + ", please attend our party this Saturday!")
