I found <a href="http://superjared.com/entry/anatomy-python-c-module/" rel="noreferrer">this</a> nice example of a Python C Module, where a single integer is passed along as the only argument. How can I instead pass a python list as argument?

Pass list as argument to Python C module?

我发现是Python C模块的一个很好的例子，它只传递一个整数作为唯一的参数。我如何才能将python列表作为参数传递？
