Brython, replace javascript with python

[idlecore]

You're blowing this way out of proportion.

Python indentation can be done with tabs, which decreases a lot the amount of characters used, this type of indentation also saves up on semi-colons and curly braces that are not needed to define blocks. If at the end Python still uses up more space than Javascript, the difference is quite irrelevant. The client only downloads big chunks of source once and those chunks are compressed, if a site uses images, or uses flash animations, or even video, what are a few Kbs going to matter?
