Finding All The Keys With the Same Value in a Python Dictionary
提问by Cobie Fisher
Let's say I have a dictionary:
假设我有一本字典：
dict = {"Jim": "y", "Bob": "y", "Ravioli": "n"} #etc...
I want to print out all the keys with the value "y" (i.e: "Jim", "Bob"). How do I do this (in the easiest way for a noobie like me to understand)?
我想打印出所有值为“y”的键（即：“Jim”、“Bob”）。我该怎么做（以我这样的菜鸟最容易理解的方式）？
*P.S. This question has already been answered here on SO, but the solutions only return one value and not all (and others I didn't understand).
*PS 这个问题已经在 SO 上得到了回答，但解决方案只返回一个值而不是全部（以及其他我不理解的值）。
PPS. It looks like everyone seems to think that it is a duplicate, but SO won't let me delete my question because it has an answer. ;(*
聚苯乙烯。看起来每个人似乎都认为它是重复的，但 SO 不会让我删除我的问题，因为它有答案。;(*

Try this,
尝试这个，
In [26]: [k for k,v in dict1.items() if v == 'y']
Out[26]: ['Bob', 'Jim']
And please don't use dictas a variable name.
并且请不要dict用作变量名。
