python - Python 模拟数据生成模块 Faker

Faker，能够为你产生各种假数据。

示例：

# coding=utf-8
"""一些生成器方法，生成随机数，手机号，以及连续数字等"""
import random
from faker import Factory

fake = Factory().create('zh_CN')


def random_phone_number():
    """随机手机号"""
    return fake.phone_number()


def random_name():
    """随机姓名"""
    return fake.name()


def random_address():
    """随机地址"""
    return fake.address()


def random_email():
    """随机email"""
    return fake.email()


def random_ipv4():
    """随机IPV4地址"""
    return fake.ipv4()


def random_str(min_chars=0, max_chars=8):
    """长度在最大值与最小值之间的随机字符串"""
    return fake.pystr(min_chars=min_chars, max_chars=max_chars)


def factory_generate_ids(starting_id=1, increment=1):
    """ 返回一个生成器函数，调用这个函数产生生成器，从starting_id开始，步长为increment。 """

            val += local_increment

    return generate_started_ids


def factory_choice_generator(values):
    """ 返回一个生成器函数，调用这个函数产生生成器，
    从给定的list中随机取一项。 """

    def choice_generator():

        while True:
