Joining 2 dictionary in python with specific value-CodePudding

i tried to join this 2 dictionary

company_detail_list = {
    'Company 1': {
        'name': 'Company 1',
        'domain': 'Retail'
    },
    'Company 2': {
        'name': 'Company 2',
        'domain': 'Construction'
    }
}

employee_detail_list = {
    'John Doe': {
        'full_name': 'John Doe',
        'company': 'Company 1'
    },
    'Tom Smith': {
        'full_name': 'Tom Smith',
        'company': 'Company 2'
    }
}

now the problem is, how do i join 2 dictionary with key of "Company" to get "domain" from dict1 to make this output:

[{
    "full_name": "John Doe",
    "company": "Company 1",
    "domain": "Retail"
}, {
    "full_name": "Tom Smith",
    "company": "Company 2",
    "domain": "Construction"
}
}]

Thanks before

You can use dict.get() and dict.update() and create your list of dicts like the below:

lst = []
for k, v in employee_detail_list.items():
    dct_tmp = v
    dct_tmp.update({'domain' : company_detail_list.get(v['company'], {}).get('domain')})
    lst.append(dct_tmp)
print(lst)

Output:

[
    {'full_name': 'John Doe', 'company': 'Company 1', 'domain': 'Retail'}, 
    {'full_name': 'Tom Smith', 'company': 'Company 2', 'domain': 'Construction'}
]
