[lug] Python Compiler Question

[Ian S. Nelson]

I believe that python automatically bytecode compiles when you import.

you could do something like
import yourprogram

yourprogram.run()

and that should do it.

There is also the py_compile module

py_compile.compile('yourcode.py', 'yourbytecode.pyc')
