使用python Fake 制造假数据/测试数据

第一次接触到Fake这个造数pyhton库，可以用来创造各种虚拟数据用来测试，记录一下一个简单的使用例子。

# pip install faker #安装
import pandas as pd 
import faker

f=faker.Faker("zh-cn") #输出为中文数据，输入“en-US”可输出英文

df=pd.DataFrame({
    "客户姓名":[f.name()for i in range(10)],
    "年龄":[f.random_int(25,40) for i in range(10)],
    "最后去点时间":[f.date_between(start_date='-1y',end_date='today')
             .strftime('%Y年%m月%d日')for i in range(10)],
    "地址":[f.street_address() for i in range(10)],
})

df

结果输出：
