人工智能基础-机器翻译
一、介绍：
它是实现机器翻译的计算机系统，它通常包括机器词典、句法语义分析规则、原语译转换规则、译语生成规则以及翻译支援系统等.
二、代码
1.translate模块中英互译
#____________________________________________________第三方模块翻译________________________________________________________ from translate import Translator class Translate: def __init__(self, file): self.file = file def english_translate_chinese(self): """英语翻译中文""" translator = Translator(to_lang="chinese") translation = translator.translate(self.file) return translation def chinese_translate_english(self): """中文翻译英语""" translator = Translator(from_lang="chinese", to_lang="english") translation = translator.translate(self.file) return translation if __name__ == '__main__': english = Translate("laboratory coat") chinese = Translate("我好喜欢你") print(english.english_translate_chinese()) print(chinese.chinese_translate_english())
