Create Dictionary of Specific Keys and Values from a Lst of Dictionaries

Question

I have a list of dictionaries which looks like this:

dic = [
 {'id': 'Team1', 'name': 'Team One', 'description': 'This is team 1', 'type': 'team'},
 {'id': 'Team2', 'name': 'Team Two', 'description': 'This is team 2', 'type': 'team'}, 
 {'id': 'Team3', 'name': 'Team Three', 'description': 'This is team 3', 'type': 'team'}
]

I want to create a dictionary of all the id values and name values so the output will look like this:

{'Team1': 'Team One', 'Team2': 'Team Two', 'Team3': 'Team Three'}

What is the best pythonic way of achieving this?

Thanks

Answer 1

Using operator.itemgetter:

from operator import itemgetter

out = dict(map(itemgetter('id', 'name'), dic))

output: {'Team1': 'Team One', 'Team2': 'Team Two', 'Team3': 'Team Three'}

used input:

dic = [{'id': 'Team1', 'name': 'Team One', 'description': 'This is team 1', 'type': 'team'},
       {'id': 'Team2', 'name': 'Team Two', 'description': 'This is team 2', 'type': 'team'},
       {'id': 'Team3', 'name': 'Team Three', 'description': 'This is team 3', 'type': 'team'}]

Answer 2

You can use dict comprehension:

dcts = [ {'id': 'Team1', 'name': 'Team One', 'description': 'This is team 1', 'type': 'team'}, {'id': 'Team2', 'name': 'Team Two', 'description': 'This is team 2', 'type': 'team'}, {'id': 'Team3', 'name': 'Team Three', 'description': 'This is team 3', 'type': 'team'} ]

output = {dct['id']: dct['name'] for dct in dcts}
print(output) # {'Team1': 'Team One', 'Team2': 'Team Two', 'Team3': 'Team Three'}

Answer 3

dictt = [ {'id': 'Team1', 'name': 'Team One', 'description': 'This is team 1', 'type': 'team'}, {'id': 'Team2', 'name': 'Team Two', 'description': 'This is team 2', 'type': 'team'}, {'id': 'Team3', 'name': 'Team Three', 'description': 'This is team 3', 'type': 'team'} ]    
new={}
for a in dictt:
    new[a['id']]=a['name']
print (new)
#{'Team1': 'Team One', 'Team2': 'Team Two', 'Team3': 'Team Three'}
