How It Works - Runtime

Not my area of expertise -- yet

• First parsed by a JavaCC parser generated from grammar file
• AST compiled to Java byte code
• Extensive Java based runtime to support byte codes
• Both JVM and PVM are stack-based virtual machines

example python module

a = 1 + 1

CPython bytecode

1           0 LOAD_CONST               1 (1)
            3 LOAD_CONST               1 (1)
            6 BINARY_ADD          
            7 STORE_FAST               0 (a)
