Table 1-1. Python Language Features

Features	Benefits
No compile or link steps	Rapid development cycle turnaround
No type declarations	Simpler, shorter, and more flexible programs
Automatic memory management	Garbage collection avoids bookkeeping code
High-level datatypes and operations	Fast development using built-in object types
Object-oriented programming	Code reuse, C++, Java, and COM integration
Embedding and extending in C	Optimization, customization, system "glue"
Classes, modules, exceptions	Modular "programming-in-the-large" support
A simple, clear syntax and design	Readability, maintainability, ease of learning
Dynamic loading of C modules	Simplified extensions, smaller binary files
Dynamic reloading of Python modules	Programs can be modified without stopping
Universal "first-class" object model	Fewer restrictions and special-case rules
Runtime program construction	Handles unforeseen needs, end-user coding
Interactive, dynamic nature	Incremental development and testing
Access to interpreter information	Metaprogramming, introspective objects
Wide interpreter portability	Cross-platform programming without ports
Compilation to portable bytecode	Execution speed, protecting source code
Standard portable GUI framework	Tkinter scripts run on X, Windows, and Macs
Standard Internet protocol support	Easy access to email, FTP, HTTP, CGI, etc.
Standard portable system calls	Platform-neutral system scripting
