Python (64-bit) for Windows

Python (64-bit) is a high-level programming language that provides an interpreted runtime, automatic memory management, and a standard library covering areas such as file handling, networking, text processing, mathematics, and system interaction. It includes a core interpreter, an interactive developer shell, and a module system for extending functionality. The language supports multiple programming paradigms, including procedural, object-oriented, and functional constructs. 

Python (64-bit) includes built-in data types, dynamic typing, exception handling, introspection, and a package management system for third-party modules. It supports large memory address spaces and modern processor architectures without changing core language behavior. 

Language structure and tooling

Python (64-bit) defines programs through indentation-based blocks, dynamic typing, and runtime name binding. Source code is compiled into bytecode and executed by the Python virtual machine. The core includes control flow statements, functions, classes, and modules. Built-in tools support reflection, namespace inspection, and runtime evaluation. The standard distribution includes command-line tools for execution, compilation, and environment configuration, along with documentation utilities and test frameworks bundled as libraries.

It includes an extensive standard library that operates as a collection of modules loaded at runtime. These modules cover areas such as operating system interfaces, subprocess control, compression formats, cryptographic primitives, date and time handling, and structured data parsing. Library components follow a unified import system and share common conventions. Many modules expose both high-level abstractions and lower-level primitives, allowing direct interaction with system resources and data formats.

The language supports external extension through packages written in Python or compiled languages. However, a global interpreter lock affects certain concurrency patterns, yet a built-in package installer manages dependency retrieval and version resolution. Python exposes a C API that allows native extensions to interact with the interpreter. Runtime configuration supports virtual environments to isolate state and libraries. The 64-bit interpreter enables extensions to allocate large memory blocks and datasets.

Harnessing the standard library

Python (64-bit) includes a core interpreter, a standardized module system, and a broad standard library that covers common programming tasks. It supports multiple programming paradigms within a single language model and allows extension through external packages. The language operates through an interpreted execution model with bytecode compilation. Objective limitations include runtime overhead associated with interpretation and reliance on external libraries for low-level hardware control or platform-specific functionality.
