内置的Python模块sqlite3是使用全局电脑的sqlite3共享库,还是静态链接?

Is the built-in Python module sqlite3 using the global computer's sqlite3 shared library, or is it statically linked?

在 Linux Ubuntu 上(使用 Python 3.5,但在较新的版本上类似),这里是内置模块 sqlite3 的调用方式:

import sqlite3 
==> sqlite3/__init__.py:    from sqlite3.dbapi2 import * 
==> sqlite3/dbapi2.py:      from _sqlite3 import * 
==> /usr/lib/python3.5/lib-dynload/_sqlite3.cpython-35m-x86_64-linux-gnu.so 

如何可靠地知道:

实际上_sqlite3.cpython-35m-x86_64-linux-gnu.so使用了一些共享库。

例子

 $ ldd /usr/lib64/python3.6/lib-dynload/_sqlite3.cpython-36m-x86_64-linux-gnu.so
