Python C extension: Use extension PYD or DLL?

I have a Python extension written in C and I wonder if I should use the file extension DLL or PYD under Windows. (And what would I use in Linux?)

Are there any differences (besides the filename)?

I found an unofficial article. Is this the secret of pyc? Why can't I find any official article on this topic?

Solution

  • pyd files are just dll files ready for python importing.

    To distinguish them from normal dlls, I recommend .pyd not .dll in windows.

    Here is the official doc about this issue:
