Python for Backend Developers
Build a practical Python foundation, from everyday syntax and control flow to references, object lifetime, and CPython optimizations.
Python foundations
In progressStart with the syntax and control flow behind a complete batch-processing script. Then follow objects through references, mutation, and reclamation before inspecting the work CPython can reuse or precompute.
Basic of Python
Types, multi-line strings, variables, functions, while and for loops, exception handling, and classes. Includes runnable examples and diagrams.
Variables and Memory in Python: References and Mutability
Names, dynamic typing, mutation through function arguments, nested aliases, shallow and deep copies, and equality versus identity.
Python Memory Management: Reference Counting and Garbage Collection
Trace strong references and unreachable cycles. Includes weak-reference experiments, explicit resource cleanup, and Python 3.14 GC behavior qualified by build and patch release.
CPython Optimizations: Interning and Constant Folding
Integer reuse, string interning, shared constants, compile-time folding, and runtime specialization, with Python 3.14 bytecode and build-specific lifetime caveats.
