Pythontoteutukset

Pythontoteutukset refers to the various implementations of the Python programming language. The most common and widely used implementation is CPython, which is written in C. CPython is the reference implementation and the one most developers are familiar with. It translates Python code into intermediate bytecode, which is then executed by the Python virtual machine.

Another significant implementation is Jython, which is written in Java. Jython allows Python code to run on the Java Virtual Machine (JVM) and interact seamlessly with Java libraries and applications. This makes it a useful tool for integrating Python into existing Java ecosystems.

IronPython is an implementation of Python for the .NET framework, developed by Microsoft. It allows Python code to run on the Common Language Runtime (CLR) and utilize the .NET libraries. This facilitates the use of Python in Windows development and other .NET-centric environments.

PyPy is an implementation that focuses on speed and performance. It uses a Just-In-Time (JIT) compiler, which compiles Python code to machine code during runtime, often resulting in significantly faster execution compared to CPython for certain types of programs. PyPy is known for its efficiency and is a popular choice for performance-critical applications.

Other less common implementations exist, each with its own specific goals and use cases, such as MicroPython for microcontrollers and Stackless Python, which modifies CPython to support microthreads. The existence of these multiple implementations contributes to Python's versatility and adaptability across various platforms and application domains.
