Usage

The library is exceptionally user-friendly, and it only requires you to import a Data Provider object that corresponds to the desired data type.

For instance, the Person provider can be imported to access 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()
'Brande Sears'

>>> person.email(domains=['example.com'])
'roccelline1878@example.com'

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

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

More about the other providers you can read in our documentation.

Locales

Mimesis presently encompasses 34 distinct locales, enabling users to specify the desired region and language when creating providers.

Here's how it operates practically:

>>> from mimesis import Person
>>> from mimesis.locales import Locale
>>> from mimesis.enums import Gender

>>> de = Person(locale=Locale.DE)
>>> en = Person(locale=Locale.EN)

>>> de.full_name(gender=Gender.FEMALE)
'Sabrina Gutermuth'

>>> en.full_name(gender=Gender.MALE)
'Layne Gallagher'

Providers

Mimesis provides more than twenty data providers which can generate a broad range of data related to food, transportation, computer hardware, people, internet, addresses, and more.

This makes it possible to generate exceedingly detailed data:

>>> from mimesis import Internet, Development
>>> from mimesis.enums import URLScheme, DSNType
>>> internet = Internet()
>>> development = Development()
>>> internet.url(scheme=URLScheme.WSS, subdomains=["chat"])
'wss://chat.system.io/'
>>> development.dsn(dsn_type=DSNType.REDIS, subdomains=["cache"])
'redis://cache.fisher.app:5432'
>>> development.dsn(dsn_type=DSNType.POSTGRES, tld_type=TLDType.CCTLD)
'postgres://posted.sy:5432'
