调用len()调用count()调用replace()完成所有操作初始状态计算长度统计字符替换字符结束 统计单词频率 除了字符频率,单词频率的统计也相对常见。可以通过str.split()方法将字符串分割为单词,并使用字典来统计每个单词的出现次数。 # 示例代码:统计单词频率defword_frequency(s):words=s.split()frequency={}forwordinword...
text = 'This is a sample text for character frequency analysis.' 接下来,我们可以使用Counter类来统计每个字符的出现次数: char_count = Counter(text) 现在,我们可以打印出每个字符及其出现的次数: for char, count in char_count.items(): print(f'{char}: {count}') 这将输出每个字符及其出现的次数。
