This can be combined with the@cython.exceptval()decorator for non-Python return types:这可以和@cython.exceptval()结合修饰非Python的返回值: Since version 0.27, Cython also supports the variable annotations defined in PEP 526. This allows to declare types of variables in a Python 3.6 compatible ...

指针(C_char)是导入可以有0值的二进制数据的推荐方法,但是似乎没有一种方法可以直接将其转换为python字符串。我看到的唯一可信的建议是使用这里推荐的c api PyString_FromStringAndSize: 我真的看不出这有什么帮助,因为afaik是一个cython特性,而不是python特性。对于感...
