列表-索引超出范围

我正在尝试熟悉python，我一直在将一些C＃代码转换为python，但遇到了一个我无法弄清楚的错误，我遇到了“索引超出范围”错误，这是我的python代码：

import random

myString = raw_input("Input: ")

words = myString.split(" ")
wordList = list()

for word in words:
    wordList.append(word) 

wordChoice = 0;
myStringRandomized = "";

while len(wordList) != 0:
    wordChoice = random.randint(0, len(wordList))
    myStringRandomized += wordList[wordChoice] + " "
    del wordList[wordChoice]

print("Characters: " + str(len(myString)))
print("Words: " + str(len(myString.split(" "))))
print("Uppercase: " + myString.upper())
print("Lowercase: " + myString.lower())
print("Randomized: " + myStringRandomized)

和C＃中的等效工作：

static void Main(string[] args)
{
    Console.Write("Input: ");
    string myString = Console.ReadLine();

    string[] words = myString.Split(' ');
    List<string> wordList = new List<string>();

    foreach (string word in words)
        wordList.Add(word);

    Random random = new Random();

    int wordChoice = 0;
    string myStringRandomized = "";

    while (wordList.Count != 0)
    {
        wordChoice = random.Next(0, wordList.Count);
        myStringRandomized += wordList[wordChoice] + " ";
        wordList.Remove(wordList[wordChoice]);
    }

    Console.WriteLine("Characters: " + myString.Length);
    Console.WriteLine("Words: " + myString.Split(' ').Length);
    Console.WriteLine("Uppercase: " + myString.ToUpper());
    Console.WriteLine("Lowercase: " + myString.ToLower());
    Console.WriteLine("Randomized: " + myStringRandomized);
    Console.ReadKey();
}

如果有人能指出我出了问题的地方，那就太好了，非常感谢！

每文档，random.randint可以包括的值b（在这种情况下，len(wordList)）。相反，您应该使用random.randrange，它是半开的（如range），并且不会包含该stop值（并且作为0默认值start，您可以将其忽略）。
