Natural language processing (NLP) is a subfield of linguistics, computer science, and artificial intelligence concerned with the interactions between computers and human language. NLP techniques are used to analyze, understand, and generate human language in a way that is both meaningful and useful. Applications include machine translation, sentiment analysis, speech recognition, and more.

Python是一种广泛使用的解释型、高级编程语言，由Guido van Rossum于1991年首次发布。Python的设计哲学强调代码的可读性和简洁性，其语法允许程序员用更少的代码行表达想法，相比C++或Java等语言更为简洁。 Python支持多种编程范式，包括面向对象编程(object-oriented programming)、命令式编程(imperative programming)和函数式编程(functional programming)。它拥有一个庞大而全面的标准库，被称为"内置电池"(batteries included)哲学。
