Usage

Import a data provider that corresponds to the data type you need.

For example, the Person provider gives access to personal information, including name, surname, email, and other related fields:

from mimesis import Person
from mimesis.locales import Locale

person = Person(Locale.EN)

person.full_name()
# Output: 'Brande Sears'

person.email(domains=['example.com'])
# Output: 'roccelline1878@example.com'

person.email(domains=['mimesis.name'], unique=True)
# Output: 'f272a05d39ec46fdac5be4ac7be45f3f@mimesis.name'

person.telephone(mask='1-4##-8##-5##3')
# Output: '1-436-896-5213'
