如何用python做词云pdf

Answer 1

，决定用python绘制词云，主要用到的是wordcloud库，安装只需要pip isntall wordcloud就行，
数据用的是酒店评论的数据，代码如下：

# -*- coding: utf-8 -*-
import matplotlib.pyplot as plt
import pickle
from wordcloud import WordCloud,STOPWORDS,ImageColorGenerator
import jieba
# import codecs

# fin = codecs.open('HotelComments.txt',mode = 'r', encoding = 'utf-8')
# print fin.read()

# 第一次运行程序时将分好的词存入文件
# text = ''
# with open('HotelComments.txt') as fin:
# for line in fin.readlines():
# line = line.strip('\n')
# text += ' '.join(jieba.cut(line))
# text += ' '
# fout = open('text.txt','wb')
# pickle.dump(text,fout)
# fout.close()

# 直接从文件读取数据
fr = open('text.txt','rb')
text = pickle.load(fr)

backgroud_Image = plt.imread('girl.jpg')
wc = WordCloud( background_color = 'white', # 设置背景颜色
mask = backgroud_Image, # 设置背景图片
max_words = 2000, # 设置最大现实的字数
stopwords = STOPWORDS, # 设置停用词
font_path = 'C:/Users/Windows/fonts/msyh.ttf',# 设置字体格式，如不设置显示不了中文
max_font_size = 50, # 设置字体最大值
random_state = 30, # 设置有多少种随机生成状态，即有多少种配色方案
)
wc.generate(text)
image_colors = ImageColorGenerator(backgroud_Image)
wc.recolor(color_func = image_colors)
plt.imshow(wc)
plt.axis('off')
plt.show()
