为python 3分配while循环中的列表

Question

我有以下一些python代码：

# we are going to define a list:

charList = []

#which we can use to add character's data to

i = 0

print("Please input data for your first character below: ")

while i <= 5:
    charList[i] = input("What is their name? ")
    i += 1 # increments i by 1
    charList[i] = input("\nAnd what is their strength value? ")
    i += 1
    charList[i] = input("\nAnd what is their skill value? ")
    i += 1
    print("\nThank You :)\n")
    print("Now for your second character:")

print(charList[0],charList[3])

这适用于3.4.0版。

它出现以下错误：

>>> 
Please input data for your first character below: 
What is their name? Chewbacca
Traceback (most recent call last):
  File "C:/Users/Peter/Documents/ARCHIVES/NEW!/Computing/task3version1.0.py", line 20, in <module>
    charList[i] = input("What is their name? ")
IndexError: list assignment index out of range
>>> 

我猜这是在while循环中改变i值的问题。 关于什么是错的任何想法？ 谢谢 ：）

Answer 1

访问列表的索引（如charList[i]中）可以访问/操作列表的现有元素。 由于charList从空开始，因此没有可访问的元素。 正如您所见，尝试这样做会给您带来超出范围的错误。

相反，你似乎想要附加到列表，如下所示：

charList.append(input("What is their name? "))

Answer 2

你为什么要在一个周期中做这件事？ 你试图重写相同的列表5次。

questions = ("What is their name? ", "\nAnd what is their strength value? ", "\nAnd what is their skill value? ")
print("Please input data for your first character below: ")
charlist = [input(i) for i in questions]
print("\nThank You :)\n")
print(charList[0],charList[3])

如果你想要几个字符：

charlist = []
questions = ("What is their name? ", "\nAnd what is their strength value? ", "\nAnd what is their skill value? ")
print("Please input data for your first character below: ")
for i in range(5):
    character = [input(i) for i in questions]
    charlist.append(character)
    print("\nThank You :)\n")
print(charList[0][0],charList[3][0])
