Can you explain what is meant by CPython and how it differs from other Python implementations?

CPython is the standard and most widely used implementation of the Python language, written in C. It compiles Python source code into bytecode, which is then executed by a virtual machine.

Differences of CPython from other implementations:

• PyPy — implements JIT compilation to speed up execution.
• Jython — implemented in Java and integrates with JVM.
• IronPython — for the .NET platform.

CPython is known for its stability, extensive library support, and is the basis for most projects. However, due to the GIL (Global Interpreter Lock), it limits the parallel execution of threads within a single process.
