APSW stands for Another Python SQLite Wrapper.
APSW is a Python wrapper for the SQLite embedded relational database engine. In contrast to other wrappers such as pysqlite it focuses on being a minimal layer over SQLite attempting just to translate the complete SQLite API into Python. The documentation has a section on the differences between APSW and pysqlite. APSW supports CPython 2.3 onwards and CPython 3.1 onwards.
