CodePudding user response：

if you have your data in a strucute like:

data = ("Demo","BRANCH_NAME","BRANCH_NAME_BUILD_NUMBER","Dummy")
# this also work for any number of strings you will have inside, like:
# data = ("Demo","BRANCH_NAME","BRANCH_NAME_BUILD_NUMBER","Dummy","foo","bar","baz")
# data = ("foo")

you can just do:

labels = [{"add": i} for i in data]

out_json = {
    "update": {
        "labels": labels
    }
}

# formatted for better readability
>>> labels
[
    {'add': 'Demo'}, 
    {'add': 'BRANCH_NAME'}, 
    {'add': 'BRANCH_NAME_BUILD_NUMBER'}, 
    {'add': 'Dummy'}
]
>>> out_json
{
    'update': {
        'labels': [
                {'add': 'Demo'}, 
                {'add': 'BRANCH_NAME'}, 
                {'add': 'BRANCH_NAME_BUILD_NUMBER'}, 
                {'add': 'Dummy'}
            ]
    }
}
