Python | How to Install python packages

This is the first video of Database programming with Python. In this video, we will see how to install the cx_Oracle package which is required to connect to the Oracle database.

We will use the command line and perform the installation using the PIP install command. pip is a de facto standard package-management system used to install and manage software packages written in Python. Many packages can be found in the default source for packages and their dependencies — Python Package Index (PyPI).

Most distributions of Python come with pip preinstalled. Python 2.7.9 and later (on the python2 series), and Python 3.4 and later include pip (pip3 for Python 3) by default.

We will also see how to uninstall any package, and how to install any specific version of the package.

The 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.

cx_Oracle 7 has been tested with Python version 2.7, and with versions 3.5 through 3.8. You can use cx_Oracle with Oracle 11.2, 12, 18 and 19 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.
