WordCloud词云库实战（二)

写在前面

昨天我们讲了英文词云绘制，今天我们来试试中文词云，首先我们需要一本道德经

读取文件

代码语言：javascript复制

#-*- coding:utf-8 -*-
with open('C:\Users\Administrator\Desktop\daode.txt',errors='ignore') as read_file:#读取文本
    data=read_file.read()
    print(data)

读取出来咋用啊，还是逐行读取为字符串吧

代码语言：javascript复制

data = ''
with open('C:\Users\Administrator\Desktop\daode.txt',errors='ignore') as f:#逐行读取文本为str
    for line in f.readlines():
        line = line.strip()
        data  = line
        print(data)

去一下标点符号

代码语言：javascript复制

from string import punctuation
str = data
add_punc='，。、【】“”：；（）《》‘’{}？！⑦()、%^>℃：.”“^-——=擅长于的&#@￥' # 去除字符串内的符号
all_punc = punctuation   add_punc
temp = []
for c in str:
    if c not in all_punc :
        temp.append(c)
newText = ''.join(temp)
print(newText)

去除数字

代码语言：javascript复制

from string import digits
s = newText
remove_digits = str.maketrans('', '', digits)#去除字符串内的数字
res = s.translate(remove_digits)
print(res)

结巴（jieba）分词

代码语言：javascript复制

import jieba
mytext = " ".join(jieba.cut(res))
print(mytext)

可视化

代码语言：javascript复制

import wordcloud
c = wordcloud.WordCloud(background_color='white')#1.配置对象参数,背景色换为白色
wenzi = "He is busy every day. He has many thing to do. He has no time to go home for lunch. He gets home at 7:00 p.m. At home he does the housework. He cooks nice dishes for mother and me."
c.generate(mytext)  #2.加载词云文本
c.to_file("pywordcloud.png")#3.输出词云文件

懵逼了吧，宝儿，这是因为matplotlib默认字体是不包含中文的，所以我们要给他的参数定义一个字体

代码语言：javascript复制

import wordcloud
c = wordcloud.WordCloud(font_path="msyh.ttc",background_color='white')#1.配置对象参数,背景色换为白色
wenzi = "He is busy every day. He has many thing to do. He has no time to go home for lunch. He gets home at 7:00 p.m. At home he does the housework. He cooks nice dishes for mother and me."
c.generate(mytext)  #2.加载词云文本
c.to_file("pywordcloud.png")#3.输出词云文件
