"Flattening" a list of dictionaries
Question: So my aim is to go from:

    
    
    fruitColourMapping = [{'apple': 'red'}, {'banana': 'yellow'}]
    

to

    
    
    finalMap = {'apple': 'red', 'banana': 'yellow'}
    

A way I got is:

    
    
     from itertools import chain
     fruits = list(chain.from_iterable([d.keys() for d in fruitColourMapping]))
     colour = list(chain.from_iterable([d.values() for d in fruitColourMapping]))
     return dict(zip(fruits, colour))
    

Is there any better more pythonic way?


Answer: 
    finalMap = {}
    for d in fruitColourMapping:
        finalMap.update(d)
