ExportData will dump the data into a pickle type format that another
Python program could read but is designed for use by the paired tool
called ImportData. If you are interested in using it for your own
purposes then read the source code and ask me questions if you run
stuck. However if you're converting your own data you could simply
write your own code using cx_Oracle with the source of cx_OracleTools
as a guide if that's helpful. cx_OracleTools is meant to be generic,
though, so it may not help you as much as you might like.

DumpData will dump the data as SQL statements that could be executed
by SQL*Plus, for example. Its intended for tables that contain a small
number of rows where someone might wish to

Using these at the command line? Or something else? All of the tools
have the --help option which will give you details on all of the
arguments and options and a description of each.

Most of the options are only needed for specialty situations. The
simplest is the following:

connection = cx_Oracle.Connection("user/password@tnsentry")

In other words, the same connect string format used by SQL*Plus. If
you want more details on the other options, look at the supplied
documentation for cx_Oracle.
