How to avoid reverse code engineering of a python executable

[NicolasG]

Hi guy's,

Couple of day's ago I asked for your help on how to create a single
file of a python executable. Now I want to proceed a little bit
further asking how can I avoid (or at least make it difficult) for
some one to extract my code by using reverse code engineer techniques?
I came on pyobfuscate but I would like more suggestions and guide to
achieve the most possible security in this matter.

Regards,
Nicoals.
