- IPython： be based on CPython An interactive interpreter on top , Enhanced interaction , The kernel is the same .CPython use >>> As a prompt ,IPython use In[ Serial number ]： As a prompt .
- PyPy： Enhanced execution speed , Yes Python Dynamic compilation of code （ It's not an explanation ）. If the code needs to be put in PyPy perform , Need to know PyPy And CPython The difference between .
- Jython： Running on the Java On the platform Python Interpreter , You can directly Python Code compiled into Java Bytecode execution .
- IronPython： and Jython be similar ,IronPython It's running at Microsoft .Net Platform interpreter , Can be Python Code compiled into .Net Bytecode .
Be careful ： and Java or .Net Platform interaction , The best way is not to choose Jython or IronPython, It is used to interact through network calls , Ensure the independence between procedures .
