本地意味着它们将在给定的目录中可用。这是通过在这个目录中放置一个文件python-version.txt来完成的。这对版本控制的存储库很重要,但是有一些不同的策略来管理它们。一种是将该文件添加到“忽略”列表中。这对开源项目的异质团队很有用。另一种方法是签入这个文件,以便在这个存储库中使用相同版本的 Python。 注意...

从南图借的这本书,已经拖了好几个月没有读完了,加紧阅读和学习一下!前面3章的笔记记在了纸上,如果有可能拍照记录一下,后面还是电子记录下,纸质的不方便和保存和查阅,也不方便分享。书的配套代码,来自异步社区:https://box.lenovo.com/l/o5OgDR

Instead, HTTPS consists of regular HTTP sent over an encrypted connection. Typically, this encrypted connection is provided by either TLS or SSL, which are cryptographic protocols that encrypt the information before it’s sent over a network. Note: TLS and SSL are extremely similar protocols, ...
