Python mode speed

I'm just asking if sketch made with python are as fast than with java mode. It's so pleasant to code in python

So, If I understand well it's the same speed.

• Both Java Mode & Python Mode are compiled as Java bytecode and run by a Java VM.
• But the "quality" of the generated bytecode varies between them.
• For example, in Java we generally use primitive datatypes to represent numerical values.
• But in Jython, everything is an object, even the numbers! @-)

P.S.: Python Mode relies on Processing's API, which is written in Java.
Therefore when using them, it's in Java's territory and got the same performance as Java Mode! :D

GoToLoop's answer is incorrect.

Python Mode sketches are interpreted, and are much, much slower than Java mode sketches. It's true that when you call a function (such as box() or ellipse()), that function is the same function called by a Java mode sketch, and therefore the same speed. But your own sketch code--your loops, your arithmetic, etc.--is much slower than it would be in Java mode.

Ok, thanks it's what I wanted to know. So for learning and simple sketch, it's perfect.
