一些Python 安装,尤其是系统安装,会禁用ensurepip。当缺少ensurepip时,有一种手动获取的方式:get-pip.py。这是一个可下载的单个文件,当执行时,它将解包pip。 幸运的是,pip是唯一需要这些奇怪的旋转来安装的包。所有其他的包都可以并且应该使用pip来安装。这包括升级pip本身,可以用pip install --upgrade pip完成。

Note that value capture happens before the guard is evaluated 如果我没理解错的话,就是先判断 pattern, True 的话再判断 guard,正常逻辑。subject 就像是一个人(本身也有主语的意思),一个个 case 就像一个个门, subject 想要看看自己能进入哪扇门,就要通过每扇门的检查。先检查你是不是个人,再检查你是不...

字典是python中唯一的映射类型，采用键值对(key-value)的形式存储数据。python对key进行哈希函数运算，根据计算的结果决定value的存储地址，所以字典是无序存储的，且key必须是可哈希的。可哈希表示key必须是不可变类型，如:数字，字符串，元组。python
