计算段落中的句子数

Question

嗨，我在这里读了所有关于计算句子和单词的主题，我不想打开任何文件，我只想计算字符串中单词和句子的数量。我已经完成了字数统计，我很高兴，我只是不知道从这里该怎么办。以下是我目前所掌握的情况。在

    import re
    line = (" A Turing machine is a device that manipulates "
            "symbols on a strip of tape according to a table "
            "of rules. Despite its simplicity, a Turing machine "
            "can be adapted to simulate the logic of any computer "
            "algorithm, and is particularly useful in explaining "
            "the functions of a CPU inside a computer. The 'Turing'"
            " machine was described by Alan Turing in 1936, who "
            "called it an""a(utomatic)-machine"". The Turing "
            "machine is not intended as a practical computing "
            "technology, but rather as a hypothetical device "
            "representing a computing machine. Turing machines "
            "help computer scientists understandthe limits of "
            "mechanical computation.")
    print (line)
    print ()
    count = len(re.findall(r'\w+', line))
    print ("The number of words in this paragraph:", count)

单词计数出来是98，这是完美的，我知道这一段有错误，但他们是故意的，所以我知道它的工作是正确的。我现在想数数句子的数量，应该是5，但我不知道怎么计算。任何帮助都将不胜感激。在

如果要依赖句点作为句子分隔符，可以计算字符串中句点的数量。在

line.count('.')

或者像您对单词使用的正则表达式：

^{pr2}$
