Hi List. All of you are right. It is similar to java, vb, but how it work? Well, python script generates a compiled bytecode the first time that yuou run the main script in a machinne, and the interpreter execute this byte code.
It could be slower than a compiled language, because use an interpreter to run, but it is faster than a interepreted language, because the interpreted language ot generated a byt code, this one reads the secripts. About operating system, it coulbe posible, but not at all. First to run an operative systems you need a low level language, like assembler, it could began the os, but the kernel could be in python. just a c library or gcc and python interpreter. if you use assembler to run with c, u can use python for your python os Alan G wrote: >>I am new to Python, about 1 day.
