first of all Python's Array do not have key and values .only have values.
use dictionary instead of Array
first approach to flip dictionary in PYTHON
dictionary = {"geeta":"good religion book" , "mahabharat":"epic peom","ramayan":"epic love story"}
results= dict(zip(dictionary.values(), dictionary.keys()))
dict.values function give all values.
dict.keys function give all keys.
zip function do very good job here . zip create an iterator of tuples, where the i-th tuple contains the i-th element from each of the argument sequences or iterables
but it return tuples convert it to dictionary by dict .
another approach to flip dictionary in PYTHON
results= [(v, k) for (k, v) in dictionary.items()]
print(results)
iterate with dictionary and get key and value and set it to another dictionary

simple way to flip associated key and values in dictionary
r= {"1":"first" , "2":"second","3":"third"}
for (k, v) in r.items():
x[v]=k
print(x)
simply iterated the dictionary and set the values value to key .
