import jieba

读取文本文件

path = "红楼梦.txt"
file = open(path, "r", encoding="utf-8")
text = file.read()
file.close()

使用jieba分词

words = jieba.lcut(text)

统计词频

counts = {}
for word in words:
# 过滤掉长度为1的词语
if len(word) == 1:
continue
# 更新字典中的词频
counts[word] = counts.get(word, 0) + 1

对字典中的键值对进行排序

items = list(counts.items())
items.sort(key=lambda x: x[1], reverse=True)

输出前20个高频词语

for i in range(20):
word, count = items[i]
print(f"{word:<10}{count:>5}")
