Python是一种简单、通用、高级和面向对象的编程语言。Python也是一种解释性脚本语言。 Guido Van Rossum被认为是Python编程的创始人。我们的Python教程包括Python编程的所有主题,如安装、控制语句、 字符串 、 列表 、 元组 、 字典 、 模块 、 异常 、日期和时间、文件I/O
为了从词汇中删除低频词,我们可以实现一个trim函数。该函数首先循环浏览单词计数词典,如果该单词的出现次数大于所需的最小计数,则将其追加到一个新的列表中。 def trim(self, min_cnt): if self.trimmed: return self.trimmed = True words_to_keep = [] for k, v in self.word2count.items(): if v ...
