python create new dict key from the value

Question

I have a array of hashes like:

detail = [{'name': 'Adam'}, {'name': 'Jackie'}]

Now what I want to do is create a new dict like:

{'name' : 'Sandra'}

What I did was:

for i in detail:
    for key_in_i in i:
        dict(key_in_i = 'Sandra')

What I would like to get is {'Name': 'Sandra'} . But if I do this I am getting {'key_in_u': 'Sandra'} because I have set the key as key_in_i . I don't know how to access the value of key from for loop to the new dict. If it was in Ruby I would have done #{key_in_i} and it would have given me the required value. I also tried new_dict = dict("%s" %key = i[key]) but it gives me error key cannot be the expression . I would be thankful if anyone could help me solve this issue!

Answer 1

The easiest solution in this particular case is

for i in detail:
    print dict.fromkeys(i, "Sandra")

You could also use a dictionary literal:

for i in detail:
    for key_in_i in i:
        {key_in_i: "Sandra"}

(Not sure what you are actually trying to achieve since your example code is effectively doing nothing.)
