引言:

  自动化脚本编写时,一般会遇到需要构造数据的情况,比如注册时的基本信息;每次执行脚本都要重新构造数据显然是很费时费力的事情,所以可以用到faker模块来构造;方便快捷,神器也;

一、安装

  pip install -U faker

二、基本用法

  1.创建10次不同的用户名:

from faker import Factory

def create_names():
    fake = Factory.create()
    ):
        print fake.name()

if __name__ == '__main__':
    create_names()

  随机产生10个符合命名规则的假数据,因为名字规则是按外国人名涉及的,所以可能会有很多概率出现姓名之外的简称等

>>>
============== RESTART: C:\Users\hao\Desktop\faker_test.py ==============
David MartinMrs. Terese Walter MDJess MayertMs. Katerina Fisher PhDMrs. Senora Purdy PhDGretchen TrompWinnie GoodwinYuridia McGlynn MDMelissa Kent April Washington >>>

  2.生成只有姓和名的数据

from faker import Factory

def create_names():
    fake = Factory.create()
    ):
        print '%s %s' % (fake.last_name(), fake.first_name())

if __name__ == '__main__':
    create_names()

  生成的数据只包含了last_name和first_name

>>>
============== RESTART: C:\Users\lizihao\Desktop\faker_test.py ==============
Gillespie Travis
Gomez Brandon
Wiley Jim
Anderson Amber
Walker Desiree
Miranda Elizabeth
Johnson Samantha
Tanner David
Keller Allison
Sanchez Kaylee
>>> 

  3.还有一些常用的数据,比如用户名、密码、电话、住址、城市等等

from faker import Factory

def create_fake_stuff():
    stuff = ['user_name', 'password', 'email', 'phone_number', 'address', 'city', 'state', 'paragraph']
    fake = Factory.create()
    for item in stuff:
        print '%s = %s' % (item, getattr(fake, item)())

if __name__ == '__main__':
    create_fake_stuff()

  生成的对应的数据:

>>>
============== RESTART: C:\Users\lizihao\Desktop\faker_test.py ==============
user_name = kevin04
password = PN5xUyd5n$
email = [email protected]
phone_number = --
address =  Brett Glens
Port Jeffrey, MD
city = Meltonbury
state = Arizona
paragraph = Iure odit voluptatibus quidem iste. Omnis ab ab voluptas consequuntur earum repellendus corrupti.
>>> 

三、其余的用法

  如果想知道faker都能生成哪些规则的数据,可以创建fake对象,然后dir(fake);

>>> from faker import Factory
>>> fake = Factory.create()
>>> dir(fake)
>>> 

  得到的结果是:

  需要什么样的数据就在里面找吧,一般都能满足你的需要;
