preface

In the process of writing programs, we often need to use a lot of data to 'test'. If you 'manually create data', you must spend a lot of energy, which is not reasonable. At this point we should use Faker, the Python library (extension package), to generate all kinds of 'pseudo-data'.Copy the code

The installation

pip install faker
Copy the code

Basic usage

from faker import Faker    Import faker from the faker module.
fake = Faker()       Save to the variable fake.
 
fake.name()           Call the name() method to randomly generate a name.
# Donna Kelly
 
fake.address()           Call the address() method to randomly generate the address information.
# 519 Donna River


If we want to generate random data in Chinese, we can pass 'zh_CN' to the locale parameter on instantiation:
from faker import Faker           
fake = Faker(locale='zh_CN')       
 
fake.name()                        
# PangChao
 
fake.address()                     
489476, Block P, Hechuan Zhang Street, Xinji County, Hebei Province


# if you want to generate traditional Chinese characters, you can pass in the value 'zh_TW' for Taiwan, China:
from faker import Faker           
fake = Faker(locale='zh_TW')       
 
fake.name()                        
# Luo Wanting
 
fake.address()                     
0, No. 35, Shuiyuan Lane, Dali County


If we want to generate data for another language or locale, we can pass in the corresponding locale:ar_EG - Arabic (Egypt) ar_PS - Arabic (Palestine) ar_SA - Arabic (Saudi Arabia) bg_BG - Bulgarian bs_BA - Bosnian cs_CZ - Czech de_DE - German dk_DK - Danish el_GR - Greek en_AU - English (Australia) en_CA - English (Canada) en_GB - English  (Great Britain) en_NZ - English (New Zealand) en_US - English (United States) es_ES - Spanish (Spain) es_MX - Spanish (Mexico) et_EE - Estonian fa_IR - Persian (Iran) fi_FI - Finnish fr_FR - French hi_IN - Hindi hr_HR - Croatian hu_HU - Hungarian hy_AM - Armenian it_IT - Italian ja_JP - Japanese ka_GE - Georgian (Georgia) ko_KR - Korean lt_LT - Lithuanian  lv_LV - Latvian ne_NP - Nepali nl_NL - Dutch (Netherlands) no_NO - Norwegian pl_PL - Polish pt_BR - Portuguese (Brazil)  pt_PT - Portuguese (Portugal) ro_RO - Romanian ru_RU - Russian sl_SI - Slovene sv_SE - Swedish tr_TR - Turkish uk_UA - Ukrainian zh_CN - Chinese (China Mainland) zh_TW - Chinese (China Taiwan)Copy the code

Faker’s other methods

Note: Individual methods are targeted. For example, the province() method is applicable to China, but not to the United States and some other countries.Copy the code
