Language Overview

A high-level comparison of Python and Go — how they differ in philosophy, tooling, and runtime behavior.

Aspect	Python	Go
Type system	Dynamically typed	Statically typed
Execution	Interpreted (bytecode on CPython)	Compiled to native binary
Formatting	PEP 8 (convention)	gofmt (enforced)
Package manager	pip / PyPI	Go Modules
Entry point	Any script can run directly	func main() in package main
Concurrency	GIL limits true parallelism; use multiprocessing or asyncio	Goroutines + channels (true parallelism)
Error handling	Exceptions (try/except)	Explicit return values (if err != nil)
OOP	Class-based inheritance	Struct + interface (composition)
Null	None (single value)	nil (typed; applies to pointers, maps, slices, channels, interfaces)
Generics	Duck typing / type hints	Generics since Go 1.18
Unused variables	Allowed	Compile error
Semicolons	Not required	Auto-inserted by compiler
