print(counter["Python"]) # 输出: 2 这里,Counter类统计了每个单词出现的次数,我们可以方便地获取"Python"的出现次数。 使用字典 对于更复杂的统计需求,可以使用字典进行自定义统计: text = "Python is an amazing language. Python is popular." words = text.split() frequency = {} for word in words: ...
text = "Python is great. Python is dynamic. Python is easy to learn." text = text.lower().translate(str.maketrans('', '', string.punctuation)) words = text.split() 2. 统计单词出现次数 接下来,我们使用count方法统计每个单词出现的次数: word_counts = {word: words.count(word) for word ...

We can also count entire words, which, as we know, are sequences of characters: s="James while John had had had had had had had had had had had a better effect on the teacher">>>s.count("had")11 .find() We search for a specific character or characters in a string with the ....
