• 词云：专门用于根据文本生成词云
• wordcloud默认会将空格，标点当作分隔符

wordcloud.WordCloud()

对于中文文本，先将其jieba拆分（返回的是列表），再用空格进行拼接

红楼梦词云

import jieba
f = open('红楼梦.txt', 'r')
txt = f.read()
f.close()

words = jieba.lcut(t)
counts = {}
for word in words:
    if len(word) == 1: # 排出单个字符的分词结果
        continue
    else:
        counts[word] == counts.get(word, 0) + 1

items = list(counts.items())
items.sort(key=lambda x:x[1], reverse=True)
for i in range(15):
    word, count = items[i]
    print("{0:<10}{1:>5}".format(word, count)

import jieba
from wordcloud import WordCloud

f = open("红楼梦.txt", 'r')
txt = f.read()
f.close()
words = jieba.lcut(txt)
newtxt = ' '.join(words)
wordcloud = WordCloud(background_color='white',width=800, height=600,
                      font_path='mysh.ttc', max_words=200, max_font_size=80,
                     ).generate(newtxt)
wordcloud.to_file('红楼梦词云.png')
