当然在Python 中并不止pickle一个模块能够进行这一操作,更原始的序列化模块如marshal,同样能够完成序列化的任务,不过两者的侧重点并不相同,marshal存在主要是为了支持 Python 的.pyc文件。现在开发时一般首选pickle。 pickle实际上可以看作一种独立的语言,通过对opcode的编写可以进行Python代码执行、覆盖变量等操作。直接编...
纯python模块(pure Python module):由python编写的模块,包含在单独的py文件中(或者是pyc/pyo文件)。 扩展模块(extension module):由实现Python的底层语言编写的模块(C/C++ for Python,Javafor Jython)。通常包含在单独的动态加载文件中,比如Unix中的so文件,windows中的DLL文件,或者是Jython扩展的java类文件。(注意,...
Installation of a C extension does not require a compiler on Linux, Windows or macOS. Allows better caching for testing and continuous integration. Creates .pyc files as part of installation to ensure they match the Python interpreter used. ...
同样地,Visual Studio Code也通过插件如"Python Extension"提供了类似的虚拟环境支持: 使用VS Code的命令面板(快捷键Ctrl + Shift + P或Cmd + Shift + P),搜索"Python: Create New Virtual Environment"命令来创建新的虚拟环境。 然后在工作区或用户设置中指定此虚拟环境作为Python的默认解释器。
首先查找名为 {modname_tail} 且包含 __init__.py、__init__.pyc 或__init__ 且带有 .so 之类的共享库文件的目录,随后查找名为 {modname_tail}.py、{modname_tail}.pyc 或{modname_tail}.{any_shared_library_extension} 的文件。如果找到符合条件的目录或文件,则创建规格对象并根据情况指定加载器: 如果...
