Python：在包含子字符串的字典中查找（字符串）键 [英] Python: Finding a (string) key in a dictionary that contains a substring

问题描述

在我的脚本中，我建立了映射到艺术家（值）的键（专辑）字典，以便我可以快速查找艺术家制作什么专辑。但是，我希望用户能够找到包含子字符串的所有相册。例如，Light的搜索应该返回

In my script I build a dictionary of keys(albums) mapped to artists(values) so that I can do a quick lookup of what artists made what albums. However, I want the user to be able to find all albums which contain a substring. For example a search on "Light" should return

[Light Chasers] = Cloud Cult 还 [Night Light] = Au Revoir Simone

最好的方法是什么？我是否应该使用字典？

What's the best way to do this? Should I even be using a dictionary?

推荐答案

[(k, v) for (k, v) in D.iteritems() if 'Light' in k]
