Implementation of processing.org's processing in pure python (processing.py runs on jython, this one runs on pure python). No dependency, no import and no run()
Release name: omri
stability: alpha, highly volatile, more to be completed
cd ppython/ppython
python ppython.py <path-to-file>/file.py
Had this project around, removed it from the fossils graveyard when Dr. Omri Har-Shemesh came to our Python meetup, inspired by his high physics background, i was reminded of this in my cupboard and decided to open it to the world.
Please don't see the source code (ppython.py) else you'll chase me out of the Python kingdom
To simply take advantage of the huge number of machine learning, data science and normal packages available
- no dependency
requires only tkinter
- no imports
you only run your code as it should. no from x import *
- no run()
no need to call run() at the end
>>> dependencies is None
TrueAbsolutely no dependency
