Hello,
Please see answer by @librebel & @karolus in this post -> best macro to detect the operating system

If you do a search on this forum you will see numerous postings for Python.
Here are some relevant links (not all from this forum):
Missing Python in LibreOffice organize macros menu
Transfer from Basic to Python
Basically python scripts reside in system, user or document storage. To embed a script in document see the EmbedPythonScriptInDocument.odt file in my answer here -> Can I embed python script and integrate with basic?
Interaction -> Christopher Bourez's blog
More here -> Information and resources for LibreOffice macros
Well, that's just some of it. There is a bunch more on the subject but that should easily get you started. Much more than I had. Found all this & more on my own when starting python & LO a couple of years ago.
Edit 2018-05-20:
Used seperate disk sitting around with almost nothing done to it after a Ubuntu 17.04 Mate install. Removed all traces of LibreOffice. Had LO 5.4.5.1 around (this is from TDF) and installed. Immediately after install ( nothing else done), the following were present:
Script provider for BeanShell extension for LibreOffice 5.4 .5.1
Script provider for JavaScript extension for LibreOffice 5.4 .5.1
Script provider for Python for LibreOffice 5.4 .5.1
Was now able to:
From menu Tools->Macros->Run Macro...
& from LibreOffice Macros successfully run HelloWorldPython
& pythonSamples->TableSample->createTable
both Python.
install LO extension I wrote, completely in python, for Calc. Executes from Toolbar. Ran without problem including various functions within dialog.
Inserted a pushbutton on Calc sheet. Connected Execute action
event to various python scripts in MyMacros
and all ran without a problem
Works for me.
