Python and sqlite
(Both are available as of now on ESX 6.5)

Python is still 3.5 version on ESX 6.5 , while widely used on now is Python 3.6. However, beauty of this fling submission is that it works with very limited support of Python as well.

Installation

SQL30 python package, sql30.egg, with applicable license can be downloaded from fling site under the file name sql30.zip. The package can also be built locally with the steps below or installed directly from pypi server ( https://pypi.org/project/sql30/ ). However, the license attached (in sql30.zip) would still be applicable to this fling.

$ virtualenv -p python3 . 
$ mkdir unpacked
$ bin/pip install --target=./unpacked/ sql30
$ cd unpacked
$ zip -r9 ../sql30.egg *
$ cd -
# 

sql30.egg file generated by above steps can now be taken and used with any machine with python3 and sqlite3 (python module) available. An example of the same is shown below. Here sql30.egg is being taken to an ESX Hypervisor with a Python 3.5.6 version and shown to consume egg file.
