how to get dictionary key inside index python

Question

i have a data that has format like this

data_lists = [{'x': '1', 'y': '2', 'z': 3}]

how if I want to get the 'x' or 'y'?

I just trying data_lists[{'x'}] , but got error ('list indices must be integers or slices, not set',)

also with data_lists[{[0]}] , the error say ("unhashable type: 'list'",)

thank you for helping me

Answer 1

data_lists = [{'x': '1', 'y': '2', 'z': 3}]
#first, iterate over the list items, which in this case there is only one
for i in data_lists:
    #then, select thee key you want
    print(i['y'])
