How to print key from its values in dictionaries in python?

Question

I have been working on operations of dictionaries . In the below code, I want to extract the key from the value. How to do it in simpler way?

dict= { "philips": "bulb", "cisca": "led"}

print(dict.values()

I want to access "philips " from "bulb"

Thankyou

You can maintain a different map {value:key}, or iterate every time over the values to extract the key — Ami Hollander, Sep 14 '19 at 10:06

print([k for k,v in dict.items() if v=='bulb'])

please note that you can have multiple keys with the same value.

>>> a = {'philips': 'bulb', 'cisca': 'led'}
>>> res = dict(zip(a.values(), a.keys()))
>>> res["bulb"]
'philips'

And if you had multiple keys with the same value of 'bulb'? – Booboo Sep 14 '19 at 12:50
