cx_Oracle version 8.3

cx_Oracle is a Python extension module that enables access to Oracle
Database. It conforms to the Python database API 2.0
specification with a considerable number of additions and a couple
of exclusions. See the
homepage for a
feature list.

cx_Oracle 8.3 has been tested with Python versions 3.6 through 3.10. You can
use cx_Oracle with Oracle 11.2, 12c, 18c, 19c and 21c client libraries.
Oracle's standard client-server version interoperability allows connection to
both older and newer databases. For example Oracle 19c client libraries can
connect to Oracle Database 11.2. Older versions of cx_Oracle may work with
older versions of Python.
