Introduction to Python Compilers
Understanding Python compilers is essential for developers looking to enhance code performance and explore different types of Python compilers. A Python compiler is a critical component of the Python programming ecosystem that transforms human-readable Python source code into low-level machine code or bytecode. Unlike Python interpreters that execute code line by line, compilers generate a compiled code version that can potentially lead to performance enhancements.
A compiler is a program that converts high-level programming language into lower-level language, which can be understood by the assembly and interpreted into logical inputs. Although many people classify Python as an interpreted language, it has different implementation versions, including CPython, Pypy, and Iron Python. CPython is a standard version that converts code into bytecode, leading to the mistaken belief that Python is interpreted. However, these interpreted codes are not understandable for the CPU unit and require an interpreter. Python Virtual Machine then converts bytecode into machine code.
