Python Flavors

  1. 1. = Python Flavors

  3. 3. Python Flavors What is Python? “Usually CPython, the most commonly used implementation of Python language is called Python even it is not true since Python is the language not the implementation. It would be possible compare the language with an interface that have the contract which could be implemented in different ways. Python have a lot of implementation like CPython, Jython, IronPython and so on”.
  4. 4. Python Flavors Is Python interpreted or compiled? “It depends of the implementation. In the most used implementation, CPython it is interpreted but with some parts pre- compiled to byte code.”
  5. 5. Python Flavors Bytecode vs Machine Code Basically the main diference between machine code is performance and portability. Machine code is faster because runs directly in CPU while bytecode is more portable because runs over a Virtual Machine. C compile the code to machine code so the code runs directly from cpu. JAVA compile the code to java bytecode and runs the code in JVM(Java Virtual Machine) Usually programmers think Python is compiled when they see the .pyc files. The .pyc files are the python bytecode that runs in the CPython VM.
  6. 6. Python Flavors Python Implementations “Why uses a alternative Python implementation? To be able to uses all the stuff regarding this technology stack, for example using Jython it is possible use all the Java stuff and libraries.” Implementation Virtual Machine Language CPython CPythonVM C Jython JVM Java IronPython CLR C# Brython Javascript Interpreter(V8) Javascript RubyPython RubyVM Ruby
  7. 7. Python Flavors Pypy a Python implementation that deserves attention PyPy is a Python interpreter and just-in-time compiler. PyPy focuses on speed, efficiency and compatibility with the original CPython interpreter. PyPy started out as a Python interpreter written in the Python language itself. Current PyPy versions are translated from RPython to C code and compiled. The PyPy JIT (short for "Just In Time") compiler is capable of turning Python code into machine code at run time. Just-in-time compilation (JIT), also known as dynamic translation, is compilation done during execution of a program – at run time – rather than prior to execution. Most often this refers to translation to machine code, which is then executed directly, but can also refer to translation to another format.
  8. 8. Python Flavors Jython a Python implementation that solve GIT problem Jython is an implementation of the Python programming language designed to run on the Java platform. Jython programs can import and use any Java class. Since Jython run over the JVM it do not implement GIT, enabling real parallelism using Threads. Global Interpreter Lock (GIT) Mechanism used in computer language interpreters to synchronize the execution of threads so that only one thread can execute at a time.
  9. 9. Python Flavors MicroPython a Python for microcontrollers Micro Python is a lean and fast implementation of the Python 3 programming language that is optimised to run on a microcontroller. The Micro Python board is a small electronic circuit board that runs Micro Python on the bare metal, and gives you a low-level Python operating system that can be used to control all kinds of electronic projects.

  10. 10. Python Flavors Conclusion ● It is possible write wherever program using just the original Python implementation and never have the necessity to use other implementation. ● It is possible to use the Python language in the main technology stacks like Java or .NET. ● Pypy could be a good solution to improve the performance of a Python application. ● It is possible to use Python in IoT projects.
