As you can see, the table contains a variety of sensitive data including names, SSNs, birthdates, and salary information. Our ‘production’ data has the following schema. Our goal will be to generate a new dataset, our synthetic dataset, that looks and feels just like the original data. The data we will use is a table of employees at a fictitious company. We obviously won’t use real data in this article we’ll use data that is already fake but we will pretend it is real. This article, however, will focus entirely on the Python flavor of Faker. It is also available in a variety of other languages such as perl, ruby, and C#. What is Fakerįaker is a python package that generates fake data. To accomplish this, we’ll use Faker, a popular python library for creating fake data. In this article we’ll look at a variety of ways to populate your dev/staging environments with high quality synthetic data that is similar to your production data. Restricting access to high quality data with which to build and test leads to a variety of issues, including making it more difficult to find bugs. WriteTo_csv() Generated output in the csv file that we just created with Pthon, Faker, and CSV libraries.New regulations around data privacy and an increasing awareness of the importance of protecting sensitive data is pushing companies to lock down access to their production data. Phone: uk_faker.phone_number() or f'+44 ) Remember that we initialized fake generators as uk_faker = Faker('en_GB') and fake = Faker().Ĭontacts Firstname: uk_faker.first_name() You will need to have uk_faker at the beginning for properties that are comming from the localization called en_GB and fake for default localization en_US. You will find below faker properties or methods that will help us build profiles for the UK companies. Let's see how we can generate it using Python and Faker. Uk_faker = Faker('en_GB') 4.) Identify Faker properties that generate the data you are after.ĭesired data sample should have columns with the following data: Unique ID, UK companies registration number, company name, companies contacts firstname, companies contacts surname, companies address, postcode, and phone. To generate UK fake data we will use localization called en_GB. In this article we are generating fake dataset with UK companies data, so we will need Faker localization for UK. Faker supports languages like Hindi, French, Spanish, Chinese, Japanese, Arabic, German and many more. It has support for variouse languages and locations. This is important because a list of random Firstnames and Lastnames in US would be diffrent to a list of random Firstnames and Lastnames in Japan.į aker.Faker() can take a locale as an argument, to return localized data. Localization allows users to specify data for which location they need Faker package to return. More detailed use of different providers is given in this notebook. Some of the fake generators for different data types are illustrated below. Full list of different faker providers can be found here. Different properties of faker generator are packaged in “providers”. 3.) Get your head around Faker Providers and Localizations.įake = Faker() initializes a fake generator which can generate data for different properties based on different data types. Now you are done with the installation and initialization of a Faker generator, and everything is ready for you to create any data you want. Let’s initialize a faker generator and start making some data: Pip install Faker 2.) Initialize Faker Generator To install the Faker package use the pip command as follows: Faker can be described as “a Python package that generates fake data for you.” By using this package we will save ourselfs time by not writing our own functions that will generete for us rundom fake values.įaker is easily installable via pip install. We will use Python package called Faker to get started. How do I make a fake dataset in Python with Faker? 1.) Install Faker package Here is how you can make a dataset with some dummy data using Python and Faker. Let’s get started making our fake yellow pages dataset! No need to scrape actual websites of business directories and break laws just to get some test data for your educational needs. Our fictional directory has structured data such as: Here we will create a dataset for an imaginary telephone directory of businesses based in the UK. What we will create using Python and Faker? This article will help you get started with Faker, talk about its rich built-in providers and generators, walk you through writing your own providers, and go over some good practices related to the use of faker. It has a rich set of predefined providers and generators for all sorts of data. Frustrated by not finding a suitable dataset? - Why not just create your own using Faker? In case you do not know about the library used in this article, Faker is a Python package that generates fake data for you.
