[Tutor] How to get Key from multiple value dictionary search

[Fosiul Alam]

Hi All,
I refer to this website
https://www.codecademy.com/forum_questions/50721fce7c7091000201e56a

dic = {'key1': ["value1",  "value2"],
       'key2': ["value77", "something"] }

what I wanted to learn is :

a) how do i get the key only by providing value i.e value77 ?

b) Please help to break the code(instead of one liner) so that i can
understand properly


Thanks.
