| PyPy This is a JIT compiler, performance is much better than the interpreter, for example, CPython is every time the Python code translated into C language, and then the C language and then translated into machine language, the cycle; PyPy this thing is the program to me when I turn it into machine language at once later.................. No later, once and for all, the disadvantage is, you put the C # writing program to stop and then restart you understand .....
