RapydScript : Python to Javascript translator
Hello, If someone is interested about a fast Python to Javascript translator (not a compiler like Brython which is another beast) Here is a link of a RapydScript Tester.

Explaining names vs variables in Python
Hello, I know Python does not have variables, but names. Multiple names cant then be bound to the same objects. So this behavior >>> b = 234 >>> v = 234 >>> b is v True according to the above that is ok But where is the consistency ? if I try : >>> v = 890 >>> w = 890 >>> v is w False It is a little difficult to explain this behavior to a newcommer in Python Can someone give me the right argument to expose ?

Experimenting with PyPyJS
Hy all, I am experimenting PyPyJS and found it not so bad at all. The virtual machine loads on a few seconds (using firefox). It s really nice for learning Python, you have all the standard libraries, and traceback on errors. I don't have to choose anymore with all transpilers around You can try it here, but please don't tell it s too long to load the VM. After all, don't you wait when you start a desktop application, or an heavy game online ? Just try it and tell your feeling Regards http://salvatore.diodev.fr/pypybox/ -- https://mail.python.org/mailman/listinfo/python-list

Nodebox(v1) on the web via RapydScript
Hello, Nodebox is a program in the spirit of Processing but for Python. The first version runs only on MAC. Tom, the creator has partly ported it to Javascript. But many of you dislike Javascript. The solution was to use a translator, Python -> Javascript Of the both two greats solutions Brython / RapydScript, I've choosen RapydScript (Brython and RapydScript does not achieve the same goal) You can see a preview of 'Nodebox on the Web' namely 'RapydBox' here : http://salvatore.pythonanywhere.com/RapydBox Regards -- https://mail.python.org/mailman/listinfo/python-list
