其他发起调用导入系统的机制 (例如importlib.import_module()) 可能会选择绕过__import__()并使用它们自己的解决方案来实现导入机制。 当一个模块首次被导入时,Python 会搜索该模块,如果找到就创建一个 module 对象 1 并初始化它。如果指定名称的模块未找到,则会引发ModuleNotFoundError。当发起调用导入机制时,Python...

If both the extension module and the source code of it are in the same directory, the extension module is loaded. Changes to the source code only have effect once you recompile. Note The option --follow-import-to works as well, but the included modules will only become importable after ...
