Inverted dictionary

Question

d = dict() #Crerating the dictionary

#Adding items to the dictionary

d['job'] = ["Scientist", "Researcher"]
d['Field'] = ["Biology", "Chemistry", "Computer science", "Healthsciences"]
d['Education'] = ["BSc","MSc","PhD"]
d['languages'] = ["French", "English", "Spanish", "Berber", "Arabic", "Turkish","Mandarin", "Japanese"]

I have this dictionary and i want to write a function that can invert the dictionary where the function will need to turn each of the list items into separate keys in the inverted dictionary.

Answer 1

invDic = lambda x: {i:j for j in x for i in x[j] }

print(invDic(d))
