流式打印出来，为啥是乱码        

django创建项目后，没有做任何修改，使用python manage.py runserver 运行项目时，提示如下报错，请问应该如何解决。

，这个盒子的目的是什么，感觉有点多余了。

为什么我修改完风格后在jupyter上显示没变化，但把代码单独拿出去用个文件运行后又是正常的？

 创建虚拟环境报错，请问题是什么原因导致的，上网看说有可能是镜像源导致的，但是我看下面的视频也切换成清华镜像源的

创建虚拟环境的后面不指定Python版本的话，会怎么样？

没有复制，跟着敲的，为什么输出的结果是“分数是{0}，等第是{1}”？

请问是出了什么问题？

 raise AssertionError(

Make sure all imports, decorators, functions, etc. needed to set up the blueprint are done before registering it.

出现这个问题改一下模块版本就行了

栈帧一调用完就消失了。global a、4是函数中的属性，是存在于堆中，不会消失。那么一旦调用了a就永远指向4了。对吧？如果是这样堆里面的100会删除吗?我感觉会删除（没人对应它了）

老师请问id（1）返回的值长度15位，转换为二进制后是47位。64位系统地址长度是不是应该64？返回值为47长度的原因是前面的0省去了吗？

老师您好，请问，上面这段代码为什么要写两个for循环？不是很理解。第一个for循环运行了三个进程，然后第二个for循环依次等待三个进程？我不理解的是，第一个for循环是否会将三个进程都运行完，然后再执行第二个for循环，依次等待?如果是这样，第一个for循环运行后，三个进程都运行了，还要第二个for循环有什么意义？ 如果稍作修改代码，如下，会有何问题？

老师，我自己写的代码，但是始终都只能生产一个馒头并获取一个馒头。请问问题出在哪里？谢谢！
