使用 map 创建嵌套字典

问题描述

我有以下变量：

LANGUAGES = ['EN','DE','FR','NL']

STOPWORDS_EN = [1,2,3,4]
STOPWORDS_DE = [5,6,7,8]
STOPWORDS_FR = [9,10,11,12]                
STOPWORDS_NL = [13,14,15,16]
STOPWORDS = [STOPWORDS_EN,STOPWORDS_DE,STOPWORDS_FR,STOPWORDS_NL]

ARTICLES_EN = ['the','a']
ARTICLES_DE = ['der','die','das']
ARTICLES_FR = ['le','la','les','las']
ARTICLES_NL = ['het','die']
ARTICLES = [ARTICLES_EN,ARTICLES_DE,ARTICLES_FR,ARTICLES_NL]

尝试 1：

{lang: {'stopwords':sw,'articles':art} for lang in LANGUAGES for sw in STOPWORDS for art in ARTICLES}

尝试 2：

{lang: {'stopwords':STOPWORDS[i],'articles':ARTICLES[i]} for lang in LANGUAGES for i in range(4)}

如何在没有循环的情况下进行，即使用单衬？

所需的输出：

{'EN': {'stopwords': [1,4],'articles': ['het','die']},'DE': {'stopwords': [5,8],'articles': ['the','a']},'FR': {'stopwords': [9,12],'articles': ['le','las']},'NL': {'stopwords': [13,16],'die']}}

谢谢

解决方法

您可以将 grey[300] 用作：

zip()

,

您可以使用enumerate()：

{ lan: {'stopwords': stop,'articles': art } for lan,stop,art in zip(LANGUAGES,STOPWORDS,ARTICLES)}
