以前生成测试字符时，用random模块拼来拼去来生成随机串，如姓名，手机，身份证等，还是费一些功夫，不过有了faker模块，一切变得简单起来

基本使用：

from faker import Faker
fake = Faker()
print fake.name()   # Jeffrey Freeman
fake = Faker("zh_CN")
print fake.name()  # 潘杨
print dir(fake)  # 可以看到所有随机方法。

自定义faker，用add_provider方法：

from faker import Faker
from faker.providers import BaseProvider
import random

class MyProvider(BaseProvider):
    def foo(self):
        return  random.random()

fake = Faker()
fake.add_provider(MyProvider)
print fake.foo()
