Everyone learns that C is compiled and Python is interpreted, then discovers Python has a bytecode compiler and JavaScript gets compiled to machine code at runtime. The clean split is mostly a lie. Here is what is actually going on.

A production guide to building high-performance Python backends with FastAPI, async SQLAlchemy, Pydantic v2, and modern deployment patterns.
