python - 如何在 Python 中声明单个数组值？

Question

我目前正在玩弄 python-jabberbot并且无法创建发送随机句子的简单方法。我不精通python所以我想知道我哪里出错了。我有一种感觉，我声明数组的方式是我的垮台:

def whatdoyouknow(self, mess, args):
        """random response"""   
        string[0] = 'this is a longish sentence about things'
        string[1] = 'this is a longish sentence about things number 2'
        string[2] = 'this is a longish sentence about things number 3'

        i = random.randint(0, 2)
        return string[i]

Answer 1

通过将元素放在方括号中来定义列表文字:

string = ['this is a longish sentence about things',
          'this is a longish sentence about things number 2',
          'this is a longish sentence about things number 3']

或者，您可以通过定义一个空列表然后附加元素来构建列表:

string = []
string.append('this is a longish sentence about things')
string.append('this is a longish sentence about things number 2')
string.append('this is a longish sentence about things number 3')

我强烈建议您阅读 Python tutorial在继续之前，它解释了构建 Python 类型以及如何为您操作它们。
