python中wordcloud库如何生成词云？

pip install wordcloud

from wordcloud import WordCloud, STOPWORDS,ImageColorGenerator

import jieba

import numpy as np

from PIL import Image

import matplotlib.pyplot as plt

import os

curpath = os.path.dirname(__file__)

filename = os.path.join(curpath, '7xi.txt')

backimg = os.path.join(curpath, 'back3.png')

savefilename = os.path.join(curpath, 'wordcloud.png')

#设置模板

backgroud_Image=np.array(Image.open(backimg))

#创建对象

wcd = WordCloud(background_color='white',width=400,height=200,font_path='simhei.ttf',mask=backgroud_Image,max_font_size=100, min_font_size=10,scale=1.5)

text=open(filename,'r',encoding='utf-8').read()

#对读取的文件进行分词

text=" ".join(jieba.lcut(text))

#生成词云

wcd.generate(text)

#保存图片

wcd.to_file(savefilename)
