Find Key by Value in Python Dictionary
September 11, 2010
It's easy to find the value given a key to a python dictionary:
lValue = lDictionary[lKey]
If you want to do the reverse, and find the value for a given key, it's possible by using a list comprehension:
lKey = [key for key, value in lDictionary.iteritems() if value == lValue][0]
