最后,我们返回这个单词个数。 为了验证函数的正确性,我们提供了一个测试字符串test_string,并调用count_words函数来计算其中的单词个数,然后将结果打印出来。 运行这段代码,你将看到输出: text The number of words in the test string is: 7 这表明测试字符串中有7个单词,验证了函数的正确性。

To count several different objects at once, you can use a Python dictionary. The dictionary keys will store the objects you want to count. The dictionary values will hold the number of repetitions of a given object, or the object’s count....
