Python列表到带有键的字典

我有以下清单：

[['Andorra', '19165'], ['Algeria', '233724']]

每个子列表中的第一个值是-country

每个子列表中的第二个值是-population

如何在此列表中创建一个字典，该字典将为子列表中的每个值设置

国家

键和

人口

键

我期待着这样的结果：

{'Country': 'Andora', 'population': '19165'}, ....

那么：

result = {country:pop for country,pop in source}

其中

source

是您的子列表

或者在外壳中：

>>> source = [['Andorra', '69165'], ['Algeria', '40375954'], ['Antigua and Barbuda', '92738'], ['Azerbaijan', '9868447'], ['Australia', '24309330'], ['Aruba', '104263'], ['Albania', '2903700'], ['American Samoa', '55602'], ['Afghanistan', '33369945'], ['Anguilla', '14763'], ['Austria', '8569633'], ['Armenia', '3026048'], ['Angola', '25830958'], ['Argentina', '43847277']]
>>> {country:pop for country,pop in source}
{'Andorra': '69165', 'Angola': '25830958', 'Austria': '8569633', 'Armenia': '3026048', 'Anguilla': '14763', 'American Samoa': '55602', 'Albania': '2903700', 'Australia': '24309330', 'Afghanistan': '33369945', 'Aruba': '104263', 'Azerbaijan': '9868447', 'Argentina': '43847277', 'Antigua and Barbuda': '92738', 'Algeria': '40375954'}

编辑 在重读你的问题之后，我认为你在寻找：

result = [{'country':country,'population':pop} for country,pop in source]

这使得：

>>> source = [['Andorra', '69165'], ['Algeria', '40375954'], ['Antigua and Barbuda', '92738'], ['Azerbaijan', '9868447'], ['Australia', '24309330'], ['Aruba', '104263'], ['Albania', '2903700'], ['American Samoa', '55602'], ['Afghanistan', '33369945'], ['Anguilla', '14763'], ['Austria', '8569633'], ['Armenia', '3026048'], ['Angola', '25830958'], ['Argentina', '43847277']]

我想这就是你要找的

[{'country': country, 'population': population} for country, population in l]

输出：
