我们意识到 imp.get_magic() 可以被 importlib.util.MAGIC_NUMBER 替代。 然后我们检查 imp.get_suffixes。 def get_suffixes(): """**DEPRECATED**""" extensions = [(s, 'rb', C_EXTENSION) for s in machinery.EXTENSION_SUFFIXES] source = [(s, 'r', PY_SOURCE) for s in machinery.SOURCE_SU...

imp.get_magic() 返回用于识别字节编译代码文件(.pyc文件)的魔术字符串值。(对于每个Python版本,此值可能不同。) imp.get_suffixes() 返回3元组元组列表,每个元组描述一个特定类型的模块。每个三元组都有这样的形式(suffix, mode, type),其中后缀是一个字符串,要附加到模块名称以形成要搜索的文件名,模式是要传...
