Python check if value is in a list of dicts

Question

I\'d like to c

Answer 1

The Proper Solution

There is a much more efficient way to do this than with looping. If you use operators.itemgetter you can do a simple if x in y check

#to simply check if the list of dicts contains the key=>value pair
'George' in map(itemgetter('name'), list_of_dicts)

#if you want to get the index 
index = map(itemgetter('name'), list_of_dicts).index("George") if 'George' in map(itemgetter('name'), list_of_dicts) else None
