vscode中python的print不能显示爬取的全部内容

[liups]

windows 10 x64，比如就这个网页https://bbs.csdn.net/topics/399085965
而windows中的命令提示符(cmd)下面则能全部显示

代码很简单，大约如下：

#coding=utf-8
import requests
import random

如果使用code runner运行，它会自动加上 -u开关 python -u "d:\TEST\python\Crawler\Crawler5.py" 经测试，就是这个-u的锅！ 临时解决办法： 设置中把Run In Terminal选项去掉，可以完整输出。 不完整的输出： 完整的输出：

[liups]

但是Run In Terminal选项还有一个问题：输出中文是乱码！还在想办法解决

https://blog.csdn.net/qq_32224299/article/details/88421101 查到上述资料，大致部分解决了问题，即code-runner配置中这一行： 是造成问题的原因，修改它，把-u部分删除，终于可以正常且完整地输出了！ 看到这个</html>终于放心了！ 引申一下，run菜单中的那些估计也有相应配置吧，简单找了一下，暂时没有找到，但是相信应该是有的，以后再说吧！
