How can get values from dictionaries of array in python?

Question

I have array which contain some firebase datas. Inside of that array I have dictionaries. Here my array:

[{'name': 'mehmet Tilsed'}, {'name': 'mahmut Tilsed'}, {'name': 'mre Tilsed'}, {'name': 'Joe Tilsed'}, {'name': 'Joe Tilsed'}, {'name': 'Joe Tilsed'}]

I want to get values of each item. How can I make it?

Here my code:

firebase = Firebase(config)

db = firebase.database()

all_users = db.child("users").child("Joe").child("users").get()

for user in all_users.each():
   userArray.append(user.val())



item1.update(userArray[2])   // In here I take only given items value. I want to get all values.

for k in item1.values():
   print(k)

for j in userArray:
    print(j)

userArray.append(user.val(),get('name')) if user.val() contains --> {'name': 'dummy'} — Vaibhav, Nov 13 '19 at 10:57

If I understand your question correctly you want to print all the names from the array right? I don't know what item1 or userArray is because you left that out but this works fine:

array = [{'name': 'mehmet Tilsed'}, {'name': 'mahmut Tilsed'}, {'name': 'mre Tilsed'}, {'name': 'Joe Tilsed'}, {'name': 'Joe Tilsed'}, {'name': 'Joe Tilsed'}]
for name in array:
        print(name['name'])

output:

mehmet Tilsed
mahmut Tilsed
mre Tilsed
Joe Tilsed
Joe Tilsed
Joe Tilsed

If you want those in a list, you can try:

from operator import itemgetter

>>> arr = [{'name': 'mehmet Tilsed'}, {'name': 'mahmut Tilsed'}, {'name': 'mre Tilsed'}, {'name': 'Joe Tilsed'}, {'name': 'Joe Tilsed'}, {'name': 'Joe Tilsed'}]

>>> lst = list(map(itemgetter('name'),arr))
>>> lst
['mehmet Tilsed',
 'mahmut Tilsed',
 'mre Tilsed',
 'Joe Tilsed',
 'Joe Tilsed',
 'Joe Tilsed']

Or,

>>> lst = [dct['name'] for dct in arr]
>>> lst
['mehmet Tilsed',
 'mahmut Tilsed',
 'mre Tilsed',
 'Joe Tilsed',
 'Joe Tilsed',
 'Joe Tilsed']
