51job词云

　　爬取的51job上的python岗位任职要求，形成了词云：

# coding:utf-8
import jieba  #分词
import  matplotlib.pyplot as plt #数据可视化
import wordcloud
from  wordcloud import WordCloud,ImageColorGenerator,STOPWORDS #词云
import numpy  as np  #科学计算
from PIL import Image  #处理图片

#打开文本
text = open("workinfo.txt","rb").read()  #rb二进制读取，
textfile=text.decode("utf-8") #按照utf-8解码
