3、python关键字提取和词云美化

第一、理论准备

1 读取图片背景
   bimg = imread(imgFilePath)
2 获取图片颜色
bimgColors=ImageColorGenerator(bimg)
3 重制词云的颜色
wordcloud.recolor(color_func=bimgColors)
 

第二、案例代码实践

import codecs;

content=[]

f=codecs.open("D:databasepython2.5红楼梦.txt",'r','utf-8')

content=f.read()

f.close()

import jieba;

import pandas;

segments=[]

jieba.load_userdict(

'D:databasepython2.5红楼梦词库.txt')

segs =jieba.cut(content)

for seg in segs:

if len(seg) >1 :

segments.append(seg);

segmentDF=pandas.DataFrame({'segment':segments})

stopwords= pandas.read_csv(

'D:databasepython2.5StopwordsCN.txt',

encoding='utf-8',

index_col=False,

quoting=3,

sep="t")

segmentDF=segmentDF[

~segmentDF.segment.
