Fake data generator in Python

Faker is a Python package that allows you to generate your own fake dataset.By using this package you can generate random data such as Name,Address,Email,City,Country etc. This package supports multiple locations and languages to generate data based on locality.

Faker is not a standard python library,so first you need to install it using following command:

pip install Faker

Following example is the simple demonstration of Faker to generate fake Name,Date of Birth, Address,country,email.

from faker import Faker#Faker instancefake=Faker()print('Name:',fake.name())print('Date of Birth:',fake.date_of_birth())print('Address:',fake.address())print('Country:',fake.country())print('Email:',fake.email())

Output

Name:Stephen PalmerDate of Birth:1984-02-24Address:880 Jones Wells Suite 398West Kimberlyfort,WI 86842Country:RomaniaEmail:[email protected]

Faker generates data by default in English US ('en_US)locale.Consider the following example to generate random names in default locale.

 from faker import Faker #Faker instance fake=Faker() print('First Name:',fake.first_name()) print('Last Name:',fake.last_name()) print('Name:',fake.name())

Output

 First Name:Jamie Last Name:Stephenson Name:Julie Davidson

To change the language we need to pass the specific locale to the Faker class.

 from faker import Faker #Faker instance in #English-India language fake Faker('en_In') print('First Name:',fake.first_name()) print('Last Name :, fake.last_name()) print('Name:',fake.name()) print('--------------') #Faker instance in #Hindi-India language fake1 Faker('hi_In') print('First Name :, fake1.first_name()) print('Last Name:',fake1.last_name()) print('Name:',fake1.name())

Output

 First Name:Dhruv Last Name:Tripathi Name:Sara Dave-------------- First Name: Last Name: Name:

List of available locales that are supported by Faker library.

 from faker.config import AVAILABLE_LOCALES #get list of available locales List=[local for local in AVAILABLE_LOCALES] #print list print(List)

Output

['ar_AA','ar_EG','ar_JO','ar_PS','ar_SA','bg_BG','bs_BA','cs_CZ','de', de_AT','de_CH','de_DE','dk_DK','el CY','el_GR','en','en_AU','en_CA','en_GB','en_IE','en_IN','en NZ','en_PH','en_TH','en_US','es','es_CA','es_ES','es MX','et EE','fa IR','fi_FI','fil PH','fr_CA','fr_CH','fr_FR','fr_QC','he_IL','hi_IN','hr_HR','hu_HU','hy_AM','id_ID','it_CH','t_IT','ja_JP','ka_GE','ko_KR','la','1b_LU','lt_LT','1v_LV','mt_MT',e_NP','n1_BE','nl_NL','no_NO','or_IN","pl_PL','pt_BR','pt_PT','ro_RO','ru_RU','sk_SK','sl_SI','sv_SE','ca_IN','th','th_TH','el_PH','tr_TR,'tw_GH','uk_UA','zh_CN','zh_TW']

There are lot of methods in Faker,you can get the list of all available attributes and methods using dir()function.

 from faker import Faker #Faker instance fake=Faker() #print list print(dir(fake))

Output

 ['__class_','_delattr_', '_dir_','__doc____',                      '_dict_',                         'address','am_pm',... 'android platform_token','ascii_company_email',        'word','words','year','zip', 'zipcode','zipcode_in_state','zipcode_plus4']
