模块在 Python 中有类型吗？
Do modules have types in Python?
我正在阅读 PEP338。有些词让我感到困惑：
If the module is found, and is of type PY_SOURCE or PY_COMPILED , then the command line is effectively reinterpreted from python <options> -m <module> <args> to python <options> <filename> <args> .
模块是否具有 Python 中的类型？
可以从不同的来源加载模块。作者提到了加载模块的 2 个具体来源，请参阅 imp module documentation:
imp.PY_SOURCE
The module was found as a source file.
[...]
imp.PY_COMPILED
The module was found as a compiled code object file.
[...]
imp.C_EXTENSION
The module was found as dynamically loadable shared library.
这些值用于 imp.get_suffixes() function 的 return 值等。
PEP 声明仅支持从源文件（.py 文件）和字节码缓存文件（.pyc）加载的模块； -m 开关不支持 C 扩展模块（通常是 .so 或 .dll 动态加载的库）。
生成的模块对象仍然只是一个模块对象；您找到的文本中的 type 一词不是指 Python 的类型系统。
模块的类型表示存储模块的文件类型，因为python文件有一些可能的类型（和扩展名。
最常见的是已编译的 python 文件（pyc 扩展名）或常规 python 纯源文件（py).
还有许多其他 py 文件扩展名，请在此处查看（几乎）完整列表：。

Proposed Semantics
The semantics proposed are fairly simple: if -m is
used to execute a module the PEP 302 import mechanisms are used to
locate the module and retrieve its compiled code, before executing the
module in accordance with the semantics for a top-level module.
现在让我们参考imp（导入机制）的文档，确定可以导入的不同类型的模块
imp.get_suffixes()
imp.get_suffixes() Return a list of 3-element tuples, each describing
a particular type of module. Each triple has the form (suffix, mode,
type), where suffix is a string to be appended to the module name to
form the filename to search for, mode is the mode string to pass to
the built-in open() function to open the file (this can be 'r' for
text files or 'rb' for binary files), and type is the file type,
which has one of the values PY_SOURCE, PY_COMPILED, or C_EXTENSION,
described below.
随后它解释了不同的类型是什么
imp.PY_SOURCE The module was found as a source file.
imp.PY_COMPILED The module was found as a compiled code object file.
imp.C_EXTENSION The module was found as dynamically loadable shared
library.
因此，PEP 338 中提到的类型只不过是可以导入的模块类型，而这些类型中只有 PY_SOURCE 或 PY_COMPILED 是上述三种类型中仅有的两种类型命令行从 python -m 有效地重新解释为 python .
