Preface

When we finish the development , We need some fake data to support our system . If you construct it yourself , laborious , It is not possible to construct appropriate data . While using python Of faker package , Constructing fake data is very simple ！

Installation tools

pip install faker

establish Faker

After installation , You need to create a Faker object , There are two ways to create , One is to create directly through the constructor , The other is to create .

>>> from faker import Faker, Factory
>>> fake1 = Factory.create() # Create by factory function
>>> fake1.name() # Randomly generate a name
'Austin Parker'
>>> fake2 = Faker() # Create by constructor
>>> fake2.name() # Randomly generate a name
'Linda Castaneda'

You can see , Created faker after , You can call name() Method to randomly generate a name .

Locale settings

The names generated above are all English names , If you want to generate Chinese names , What to do ？

Faker Support setting localization when creating , That is, the designated area .

>>> fake = Faker("zh_CN")
>>> fake.name()
' Xi Jianping '

You can see , After setting localization , Chinese names can be randomly generated .
