(5条消息) python抓数据处理、python django127.0.0.1:8000可以运行，127.0.0.1:8000/admin不可以运行、network三个测试类

python django127.0.0.1:8000可以运行，127.0.0.1:8000/admin不可以运行

关于在windows下使用pycharm开发Django进入admin页面时弹出python已停止运行

可能是Django版本问题
卸载安装

使用pip命令来 卸载 Django

 pip uninstall django

python抓数据处理

import wordcloud
file = open(r"D:\PyCharm实例\抓数据\最多收藏.txt",encoding="utf-8")
text = file.read()
wc = wordcloud.WordCloud()
wc.generate(text)
image = wc.to_image()
#stopwords = {" "}
#wc = wordcloud.WordCloud(font_path=r"D:\PyCharm实例\抓数据\STSONG.TTF",stopwords=stopwords)
wc = wordcloud.WordCloud(font_path=r"D:\PyCharm实例\抓数据\STSONG.TTF")
wc.generate(text)
image = wc.to_image()
image.show()
