What is the precedence of python compiled files in imports?

问题

Python files are compiled to bytecode (*.pyc).

Using Cython you can compile them to machine code (*.so in Linux).

If you use have both files in the same folder, under the same name what is the precedence between them?

Is there an automatic way to ensure that the *.so file is used instead of the *.pyc one? Or you have to do it explicitly in the code (renaming etc)?

回答1:

Python will load the .so file first. See this question for an ordered list of the suffixes that python searches for.

Well, I'll just tell you:

foo (a directory)
foo.so
foomodule.so
foo.py
foo.pyc
